Add a driver for the regulators found on the MT6363 PMIC, fully
controlled by SPMI interface.
This PMIC regulates voltage with an input range of 2.6-5.0V, and
features 10 buck converters and 26 LDOs.

Add a driver for the regulators found on the MediaTek MT6373 PMIC,
fully controlled by SPMI interface.
Similarly to MT6363, this PMIC regulates voltage with input range
of 2.6-5.0V, and features 10 buck converters and 25 LDOs.
This PMIC is usually found on board designs using the MT6991 or
MT8196 SoC, in combination with the MT6363 PMIC.
