u8500: shrm: Add support for RTC Calib messages
A new shared-mem IPC logical channel (mapID=200) allows APE
to send and receive messages to the modem in support of the
calibration of the RealTimeClock.
The modem can measure the 32KHz clock drift (against network clock)
and report the drift to the APE. This new logical channel supports
this reporting and can be accessed via a new /dev/rtc_calibration
device.
