regulator: add QCOM RPMh regulator driver
Add the QCOM RPMh regulator driver to manage PMIC regulators which are controlled via RPMh on some Qualcomm Technologies, Inc. SoCs. RPMh is a hardware block which contains several accelerators which are used to manage various hardware resources that are shared between the processors of the SoC. The final hardware state of a regulator is determined within RPMh by performing max aggregation of the requests made by all of the processors. Add support for PMIC regulator control via the voltage regulator manager (VRM) and oscillator buffer (XOB) RPMh accelerators. VRM supports manipulation of enable state, voltage, and mode. XOB supports manipulation of enable state.
