[PATCH v3 2/5] dt-bindings: soc: loongson,ls2k-pmc: Use fallbacks for ls2k-pmc compatible

[Binbin Zhou <zhoubinbin@xxxxxxxxxxx>]

The Loongson-2K series chips (ls2k0500/ls2k1000/ls2k2000) share the same
PM system controller, using ls2k0500 compatible as fallback for the
others.

Fixes: 6054a676e969 ("soc: dt-bindings: add loongson-2 pm")
