soc/mediatek/mt8192: Add board-specific regulator APIs
To enable DVFS, DRAM driver needs to access four different
regulators that SoC can't access directly and need board-specific
implementations.
To support that we need to define the getter and setter APIs for
those regulators.
BUG=b:147789962
BRANCH=none
TEST=verified with DRAM driver
