Power off control pin on Thinknode m5 during deepsleep and add RTC (#9510)

Browse Source 
* Power off control pin on Thinknode m5 during deepsleep

* Apply suggestion from @Copilot

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Finish HAS_RTC cleanup

* Add RTC for Thinknode M5

* Don't double-init Wire

* Specify the RTC chip directly rather than use SensorRtcHelper.
Saves a bit of flash, and avoid mis-detection
