When support for the MT6366 PMIC regulators was added, it was assumed
that it had the same functionality as MT6358. In reality there are
differences. A few regulators have different ranges, or were renamed
and repurposed, or removed altogether.
Add the 3 regulators that were missing from the original submission.
These are added for completeness. VSRAM_CORE is not used in existing
projects. VM18 and VMDDR feed DRAM related consumers, and are not used
in-kernel.
