Added RTC TICK as wakeup source.
When the vibrator is running the DEEP IDLE state with TOP=ON is used.
The SD/MMC interface S3C_DEV_HSMMC2 is not checked for activity (on the
NS4G this interface is active while 4G is enabled).
For the DEEP IDLE state with TOP=OFF the original GPIO power down control
and pull up-down configurations are saved and restored after wakeup.
Added Battery Life eXtender (BLX) version 1.
