The DT bindings for MT6366 regulator defines the supply names for the
PMIC.
Add support for them by adding .supply_name field settings for each
regulator. The buck regulators each have their own supply whose name
can be derived from the regulator name. The LDOs have shared supplies.

Changes since v2: none
Changes since v1:
- Replaced underscores in supply names with hyphens
- Reflowed a couple macros for readability
