Guillaume Revaillot 38b45c8786 stm32g0: add adc.
v2 "single" peripheral with a couple of tweaks :
 - added registers to configure two additionnal advanced analog watchdog.
 - different adc sampling time time based on channel groups.
 - 8 steps adc sequence injection, using chselr/chselrmode.

And a note on the rm explaining that after every configuration change to ADC_CFGR1's
SCANDIR or CHSELRMOD or CHSELR register, user need to check that configuration
is applied before any other modification / adc conversion start.. making adc_set_reqular
a bit painfull to read..
