- system_power portion of drivers/adc split into a new standalone module (drivers/system_power)
- additional availability flags added to system_power.msg so we know what boards even support (previously certain flags were faked if not available)
- drivers/system_power scheduled at minimum rate by default, but now also scheduled immediately on any relevant GPIO events
- now instead of running at 100 Hz with heavily reduced logging we can run at a minimal rate, log at full rate, and catch relevant changes immediately
- fmu-v5 debug and stackcheck builds now need to be CONSTRAINED_FLASH to fit
- delete unused holybro_durandal-v1_stackcheck build (also CONSTRAINED_FLASH)
