[PATCH v1 3/5] regulator: mtk-dvfsrc: Add support for Dimensity 1200 MT6893

[AngeloGioacchino Del Regno]

The MediaTek Dimensity 1200 (MT6893) features the same DVFSRC
regulators as the other currently supported SoCs, but with a
different select value: add an array describing the possible
voltages for the VCORE and VSCP regulators, and assign it to
a new compatible for this SoC.
