Subject: [PATCH 2/9] mfd: mt6358: Add registers for MT6366 specific regulators

The MT6366 PMIC, compared to the MT6358, does away with the VCAM*
regulators. Two regulators VM18 and VMDDR reuse their register space.
There's also a VSRAM type regulator VSRAM_CORE thats' split between
the VCAM* register space and other parts.

Add register address macros for these MT6366 specific regulators.
