Rather then open coding a cache of the vibra control registers use the
regmap cache code.  Also cache the interrupt mask register, providing

The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.

2. Add pcr->ops->force_power_down to fulfill the individual action for

ADC is ideally expected to work at a frequency of 3MHz.
The present code had a check, which returned error if the frequency
went below the threshold  value. But since AM335x supports various
working frequencies, this check is not required.
Now the code just uses the internal ADC clock divider to set the ADC
frequency w.r.t the sys clock.
