[PATCH 3/4] regulator: spacemit-p1: Update supply names

Update supply names to match the P1 PMIC's actual hardware pinout where
each buck has an individual VIN pin (vin1-vin6) and LDO groups have
dedicated input pins (aldoin, dldoin1, dldoin2).
The supply is a board design decision and should not be hardcoded to any
existing power source. This allows boards to specify their actual power
tree topology in devicetree.
