CONFIG_CLOCK_STM32_APB2_PRESCALER does not exist for STM32F0 as it was
removed from the RCC Kconfig by commit d0678201c3 ("drivers:
clock_control: provide support for stm32f0."). This will break the PWM
driver if compiled for STM32F0.
Conditionally disable usage of this symbol for STM32F0 as all PWMs are
on APB1 for this family.

The prescalers are currently hardcoded and are not user-selectable. As a
result, the frequency of the timer can be inadequate to the task. For
instance, the frequency of the 16-bit timers (prescaler 10000) is
usually too low to correctly generate of PWM of a few kilohertz.
Hardcoded prescalers are replaced by Kconfigs so the user can choose at
compile time. The default value of each Kconfig matches the hardcoded
prescaler, so the change will be transparent.

All the PWM between 1 and 20 can be found on the STM32 depending on the

The registration of each PWM differs only by a few details.
These differences can be factorized in order to create a generic
registration macro.
This has several advantages:
- Less code
- Easier to add new PWM

This commit removes the arm_mpu_enabled status flag in the ARM
MPU driver. This flag is not needed, because the value of the
MPU_CTRL register stays the same while the MPU is enabled, and
is cleared to 0 when the MPU is disabled. Therefore, we do not
need to prevent from having the enable or the disable operation
to be called multiple times.

ARM Cortex-M0+, M3, and M4 MCUs have a fixed number of 8 MPU
regions, if MPU support is implemented. Therefore, we can
implement _get_num_regions() to return a constant, if CPU
is one of the above Cortex variants. _get_num_regions() is
invoked often in the code, so this solution increases processing
efficiency. A sanity check is implemented in arm_mpu_init(), to
ASSERT if the number of regions provided by hardware does not
match the expected (default) value.

Functions for per-interface statistics collection used a pointer to a
packet that could've been deallocated in the net_conn callback function.
In result, application could crash when interface related to the packet
was referenced. To fix that, packet interface is stored earlier, so it
can be used instead for statistics collection.

Users are sometimes mistakenly invoking cmake with $ZEPHYR_BASE set as
the source directory.
This user-error can occur if the user believes that the toplevel
CMakeLists.txt file is at the root of the repo, or if the user uses
the wrong path when invoking cmake.
The error given when this user-error occurs is cryptic and undefined,
so we replace it with what should be an easy-to-understand error
