As per the DM[1] Dated June 2016–Revised February 2017, Table 5-3,
DRA71 supports the following OPPs for various voltage domains:
VDD_MPU: OPP_NOM
VDD_CORE: OPP_NOM
VDD_GPU: OPP_NOM
VDD_DSPEVE: OPP_NOM, OPP_HIGH
VDD_IVA: OPP_NOM, OPP_HIGH
This patch add support for selection of the above OPPs instead of
using OPP_NOM for all voltage domains.

Changes since v1:
- Updated efuse reg bits for OPP_HIGH as pointed out by Suman.
