Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.
Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.
Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

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.

CONFIG_BOARD_FOO is enabled in a number of board *_defconfig files
although it is useless as it is set by default (as defined as a
one option choice, symbol defaults to 'y').
CONFIG_BOARD_FOO should remain only in target that are defined
in boards providing multiple choices (dual cores, board with multiple
revisions).

dts pinctrl definitions were pushed in tree without the code
available to deal with it. They have been kept waiting for the
code, but this is taking much more time than initially thought.
So in current zephyr tree, for all STM32 boards, we have pinmux.c
file which is used to configure pins and these files that are
basically no-op. This situation is creating a lot of confusion
especially to new comers, and create useless maintenance effort.
Remove these files for now.

STM32 clock control subsystem allows to configure a different
frequency value for core clock (SYSCLK) and AHB clock (HCLK).
Though, it is HCLK which is used to feed Cortex Systick timer
which is used in zephyr as reference system clock.
If HCLK frequency is configured to a different value from SYSCLK
frequency, whole system is exposed to desynchro between zephyr clock
subsytem and STM32 HW configuration.
To prevent this, and until zephyr clock subsystem is changed to be
aware of this potential configuration, enforce AHB prescaler value
to 1 (which is current default value in use for all STM32 based
boards).
On STM32H7, enforce D1CPRE which fills the same role as ABH precaler.
On STM32MP1, the equivalent setting is done on A7 core, so it is
not exposed to the same issue as long as SYS_CLOCK_HW_CYCLES_PER_SEC
is set with the 'mlhclk_ck' clock frequency value. Update
matching boards documentation.
