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.
