hekate: clear rtc interrupt and stop alarm

Browse source 
Stopping rtc alarm is now done in the function that actually checks it, in order to avoid power offs from HOS if it's fired and user wants to continue booting.

Additionally, clear the interrupt which is the actual thing that is checked by HOS.
