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outdated stuff easy to catch.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).
Clean it from STM32 impacted boards.

Move systick activation in soc/ as a Kconfig.defconfig file and
remove activation in boards _defconfig files.
This will allow to deactivate it in a more flexible way
with upcoming LPTIMER as tick source when power management
features are enabled.

These all have what appears to be a promiscuously cut-and-pasted
declaration for a 1000 Hz tick rate. They are all SysTick boards and
will work very well with the new 10 kHz default, so use that instead.

We shall not enable by default a system timer in ARM
platforms, namely the SysTick, the Nordic, or the SAM0
RTC timer, simply by assessing the hardware capabilities
(e.g. by conditioning on CPU_CORTEX_M_HAS_SYSTICK).
Instead, now, all ARM platforms needs to explicitly set
their system timer module. Note that this has already
been the case for ca 80% of the ARM platforms.
This clean-up allows us to decouple HW capabilities from
system configuration (for example, Nordic platforms may
enable option CPU_CORTEX_M_HAS_SYSTICK, and still use
the platform-specific RTC timer for system timing).

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

The STM32_ARM_MPU_ENABLE option is just selecting ARM_MPU option,
which could be also controlled through menuconfig.
This commit removes the STM32_ARM_MPU_ENABLE option and replaces
its usage by ARM_MPU option.

This commits align CONFIG_ factor names between stm32f4 and stm32l4
series to enable code factorization such as use of Q_DIVISOR.
Though, it does not concatenate kconfig sections as we might use
a bit of time to see what is needed in this regard

This commit provides CONFIG_ definitions to support
LL based clock driver on stm32f4 boards:
96b_carbon
nucleo_f401re
nucleo_f411re
This commit sticks to clock configurations previously defined.
Two changes to notice:
-HSE clock value should now be defined
-Prescaler values required as "1" should now be set to "1" instead
of "0".
