This updates the clock handling in the DB8500 PRCMU driver with
the latest findings and API changes related to changes in the
backing firmware in the PRCMU.
- Add the necessary interfaces to get the frequencies of the
clocks and set the rate of some of the clocks.
- Add support for controlling the clocks PLLSOC0, PLLDSI,
DSI0, DSI1 and DSI escape clocks (DSInESCCLK).
- Correct the PLLSDI enable/disable sequence by using the
DSIPLL_CLAMPI bit.
After this we will have the interfaces and code to implement the
U8500 clock framework properly.
