[PATCH 3/9] mfd: mt6397: Split MediaTek MT6366 PMIC out of MT6358

[Chen-Yu Tsai]

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, but has additional VM18, VMDDR, and VSRAM_CORE LDOs.

Add a separate compatible for the MT6366 PMIC. The regulator cell for
this new entry uses a new compatible string matching MT6366.

Fixes: c47383f84909 ("mfd: Add support for the MediaTek MT6366 PMIC")
