mfd: dt-bindings: mt6397: Add regulator supplies

Browse Source 
On the MT6397 family each buck regulator has a separate supply. LDOs are
split into various groups with independent supplies. There is also a
supply for the regulator control logic.

Add descriptions for all of the supplies for the MT6359.
