regulator: rpmh-regulator: Add RPMH regulator support for Glymur
Add support for PMH0101/PMCX0102/PMH0110/PMH0104 PMIC voltage regulators which are present on Glymur boards. Introduce new LDOs & SMPSs under them (PMIC5 subtype 530 for both). For these new LDOs support a new optimum power mode(OPM). In this mode LDO will automatically switch between high power mode (HPM) and low power mode (LPM) based on the real-time LDO load current. Its operation is analogous to SMPS AUTO mode.
