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