ARM: DRA7: Add ABB setup for all domains
ABB should be initialized for all required domains voltage domain
for DRA7: IVA, GPU, EVE in addition to the existing MPU domain. If
we do not do this, kernel configuring just the frequency using the
default boot loader configured voltage can fail on many corner lot
units and has been hard to debug. This specifically is a concern with
DRA7 generation of SoCs since other than VDD_MPU, all other domains
are only permitted to setup the voltages to required OPP only at boot.
