danicampora 2c103d5200 cc3200: Rewrite the PRCM RTC functionality methods.
This allows to use the On-Chip retention registers for both the
RTC and to share notification flags between the bootloader and the
application. The two flags being shared right now are the "safe boot"
request and the WDT reset cause. we still have 2 more bits free for
future use.
