RTC backup battery

The RTC block in CCONT needs a power backup to keep the clock run-
ning when the phone battery is disconnected. The backup power is sup-
plied from a rechargable polyacene battery that can keep the clock run-
ning ten minutes minimum. The backup battery is charged from the main
battery through CHAPS.
