[U-Boot] [PATCH 1/4] ARM: DRA7: Update/Correct MPU and CORE OPP_NOM voltage values

The current OPP_NOM voltage values defined for the MPU and CORE
voltage domains are based on the initial DRA75x_74x_SR1.1_DM data
manual. As per this DM, the PMIC boot voltage can be set to either
1.10V or 1.15V for VD_MPU, and either 1.06V or 1.15V for VD_CORE.
While the current values are correct, the latter set of values
are the values that are common across all DRA75x, DRA72x SoCs and
for all current Silicon revisions. So, update both the MPU and CORE
OPP_NOM voltages to 1.15V.

The macros are also slightly reorganized so that both the MPU and
CORE voltage domain values are defined together.
