[PATCH v2 00/18] Add support to STMicroelectronics STM32 family

[Maxime Coquelin]

Thanks for the first round of reviews.
Most of the comments made have been taken into account (see below for details),
except that I failed to find an easy/clean way to move vector_table location in
order to limit the waste of memory.
If you have any idea/example to do that, I will be pleased to add it in next
version of the series.

STM32 MCUs are Cortex-M CPU, used in various applications (consumer
electronics, industrial applications, hobbyists...).
Datasheets, user and programming manuals are publicly available on
STMicroelectronics website.

With this series applied, the STM32F419 Discovery can boot succesfully.

Changes since v1:
-----------------
 - Move bindings documentation in their own patches (Andreas)
 - Rename ARM System timer to armv7m-systick (Rob)
 - Add clock-frequency property handling in armv7m-systick (Rob)
 - Re-factor the reset controllers into a single controller (Philipp)
 - Add kerneldoc to reset_controller_of_init (Philipp)
 - Add named constants in include/dt-bindings/reset/ (Philipp)
 - Make pinctrl driver to depend on ARCH_STM32 or COMPILE_TEST (Geert)
 - Introduce CPUV7M_NUM_IRQ config flag to indicate the number of interrupts
supported by the MCU, in order to limit memory waste in vectors' table (Uwe)
