platform: cznic: turris-omnia-mcu: Make poweroff and wakeup code optional
Make the system poweroff and RTC wakeup part of the driver optional,
under a boolean config option. Move the dependency to RTC_CLASS to this
new option.
This makes the turris-omnia-mcu driver available for compilation even if
RTC_CLASS is disabled.
