=46rom: Matti Vaittinen <[email protected]>

The commonly used ROHM PMIC bindings were added into
rohm,pmic-pins.yaml. Keeping commonly used properties in one file can
ease both the maintaining the bindings and the reviewing process.

Reference the common bindings from rohm,pmic-pins.yaml, instead of
declaring them from the scratch for every PMIC using them. Keep the PMIC
variant specific information (like supported pin functions) in PMIC the
specific files, so unsupported values won't be allowed.
