We rework the timer driver for Cortex-M0 QEMU Board.
The driver is adapted to follow the (recent) nRF RTC
driver logic, and adaptations are made simply because
the driver is based on the TIMER peripheral instead of
the RTC.
A couple of tweaks are added due to QEMU issues with the
simulation of the TIMER peripheral.

Remove prompts from Kconfig options `UART_x_NRF_UART*` that select
the type of nrfx driver (for UART or UARTE peripheral) to be used
for a given instance. This prevents the options from being modified
from configuration files.
Instead, make one of these options selected by default according to the
"compatible" property set for the corresponding UART node in devicetree.
This eliminates the need of changing both the "compatible" property in
devicetree and the Kconfig option selecting the driver type when a user
wants to switch between UART and UARTE for a given instance.
Since all `UART_x_NRF_UART*` options are made "hidden" by this commit,
all their occurrences in configuration files are removed.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.
CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.
Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:
1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
turn the CONFIG_<arch> symbols into invisible
(promptless/nonconfigurable) symbols instead.
Getting rid of the choice allows the symbols to be 'select'ed (choice
symbols don't support 'select').
2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
This makes sense since you know the architecture if you know the SoC.
Put the select on the SOC_* symbol instead for boards that don't have
a SOC_SERIES_*.
3. Remove all assignments to CONFIG_<arch> symbols. The assignments
would generate errors now, since the symbols are promptless.
The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.
See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.
This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single
interrupt. The split was done probably because opaque subsys
argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.
Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create
multiple devices - mess.

Also change all <description>s from

Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.
config FOO
int
default 3
Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):
For a symbol defined in multiple locations (e.g., in a
Kconfig.defconfig file in Zephyr), it is best to only give the
symbol type for the "base" definition of the symbol, and to use
'default' (instead of 'def_<type>' value) for the remaining
definitions. That way, if the base definition of the symbol is
removed, the symbol ends up without a type, which generates a
warning that points to the other definitions. That makes the extra
definitions easier to discover and remove.
It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.
Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.
