--------------------------------
[ Upstream commit 61fdd1f1d2c183ec256527d16d75e75c3582af82 ]
The MT6366 PMIC is mostly, but not fully, compatible with MT6358. 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.
