regulator: dt-bindings: mt6358: Add regulator supplies

The MT6358 PMIC has various regulator power supply pins that should be
supplied from external power sources or routed from one of its outputs.

Add these regulator supplies to the binding. The names are the actual
names from the datasheet, with hyphens replacing underscores.
