ARM: dts: msm: remap PMIC regulators for sm8150-auto

The power grid for sm8150-auto differs substantially from that
of baseline sm8150.

PMIC Combinations:
SM8150:      PM855 + PM855L + PM855B + PM8009
SM8150 Auto: PM855 + PM855

Add all rpmh-regulator devices supported by SM8150 Auto and remap
SoC level PMIC regulator phandles to match the SM8150 Auto power
grid.
