msm: clock-8960: Use VDD dig corner regulator for 8930.

Browse Source 
The VDD dig corner regulator allows voting on the logical VDD dig levels
without having to deal with the specific voltages that correspond to each
logical VDD dig level. This allows the RPM to optimize the actual voltage
that corresponds to each logical level based on hardware characteristics.
