ARM: OMAP5: DRA7xx: support class 0 optimized voltages

Browse Source 
DRA752 now uses AVS Class 0 voltages which are voltages in efuse.

This means that we can now use the optimized voltages which are
stored as mV values in efuse and program PMIC accordingly.

This allows us to go with higher OPP as needed in the system without
the need for implementing complex AVS logic.
