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).
This is an ABI change from the original "vin" and "buck5" supplies.
The P1/PMIC regulator has no consumers in the DTS tree yet. For the two
K1 boards in-tree (BPI-F3 and Jupiter), power settings come from
boot firmware, so a probe failure has minimal impact.
