drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVI
On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider (RTC_DIV) that divides the input 32.768KHz clock to the frequency that users need (E.g. 1 Hz). The divided real-time clock will be used to drive a 32-bit counter (RTC_COUNTER) that provides users with the actual time. In each cycle of the divided real-time clock, there is a Hertz interrupt generated to the RISC. Users can also configure an alarm (RTC_ALARM). When RTC_COUNTER matches the alarm, there will be an alarm interrupt generated to the RISC. The system RTC can generate an alarm wake-up signal to notify the power controller to wake up from power saving mode.
