regulator: dt-bindings: nxp,pca9450: document input supplies 

Add missing supply properties for PCA945x input pin groups:
- inl1-supply (for LDOs)
- inb13-supply (for BUCK1/3)
- inb26-supply (for BUCK2/6)
- inb45-supply (for BUCK4/5)

These properties describe external power sources for each input group.
