Optional:
PM8010 L1 and L2 physically support LPM vs HPM configuration.
Therefore, these lines could be added here to allow such configuration
by software at runtime:

regulator-allow-set-load;
regulator-allowed-modes = <RPMH_REGULATOR_MODE_LPM
RPMH_REGULATOR_MODE_HPM>;

David,

I was under the impression that *all* RPMh regulators support
modesetting. Would that be an incorrect assumption to make?
