This patch adds new chip family, stm32wl5x. This is bare minimum
implementation of said chip. I've tested this by running nsh.
There are only two chips in this family, stm32wl55 and stm32wl54.
The only difference between them is that stm32wl55 has LORA.
stm32wl5 is dual CPU (not core!). Right now only CPU1 is implemented.
CPU0 has access to radio hardware (while CPU1 does not). Chip is
designed so that CPU0 handles radio traffic while CPU1 does the
heavy lifting with data - there is communication pipe between two
CPUs.
I plan to use nuttx on CPU1 and LORA from stm32cube on CPU0 so I
don't have implementing CPU0 right now - once we have working LORA
in nuttx this may change.
Peripherals (except for radio) are shared so it's best to focus on
CPU1 to initialize all peripherals so that CPU0 can only use them
later. There is no real benefit to implement CPU0 if we don't have
working LORA/radio support in nuttx.
In time I will be implementing more and more things from this chip.
Right now I would like this minimal implementation to be merged in
case someone wants to work on this chip as well.
