[PATCH v3 1/3] dt-bindings: regulator: Add MAX77675 binding header

[Joan-Na-adi <joan.na.devcode@gmail.com>]

From: Joan Na <joan.na@analog.com>

Add binding header for the MAX77675 PMIC regulator. This header defines
voltage ID and regulator index macros used both in device tree sources
and in the driver implementation.

Fixes:
- Removed unused macros
- Renamed macros for clarity
