It has a different set of regulators. Specifically, it lacks the camera related VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs. The PMICs contain a chip ID register that can be used to detect which exact model is preset, so it is possible to share a common base compatible string. Add a separate compatible for the MT6366 PMIC, with a fallback to the MT6358 PMIC.
