Subject: [PATCH v1 3/6] dt-bindings: regulator: Document MediaTek MT6363 PMIC Regulators

Add bindings for the regulators found in the MediaTek MT6363 PMIC,
usually found in board designs using the MT6991 Dimensity 9400 and
on MT8196 Kompanio SoC for Chromebooks, along with the MT6316 and
MT6373 PMICs.

+description:
+  The MT6363 SPMI PMIC provides 10 BUCK and 26 LDO (Low Dropout) regulators
+  and can optionally provide overcurrent warnings with one ocp interrupt
+  for each voltage regulator.

+      Names for the overcurrent interrupts are the same as the name
+      of a regulator (hence the same as each regulator's node name).
+      For example, the interrupt name for regulator vs2 will be "vs2".
