[PATCH 4/4] riscv: dts: spacemit: k1-bananapi-f3: Update PMIC supply properties

Update individual supply properties in pmic node to accurately specify
the board's power tree topology.

Previously these relationships were hardcoded in the driver; now they
are explicitly defined in the devicetree per the updated binding
document spacemit,p1.yaml.
