dt-bindings: mfd: mt6397: Split out compatible for MediaTek MT6366 PMIC

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.
