rtc: add driver for MXC's internal RTC module
This adds a driver for Freescale's MXC internal real time clock modules.
The code is taken from Freescale's BSPs, but modified to fit the current
kernel coding mechanisms. Also, the PMIC external clock function was
removed for now to not add dead bits and keep the code as simple as
possible.
