[PATCH v3 3/5] dt-bindings: mfd: syscon: Allow syscon compatible for Loongson-2K0300 chip id

The Loongson-2K0300 SoC exposes its chip ID registers through a syscon
interface. Add the specific compatible `loongson,ls2k0300-chipid-syscon`
to the allowed list of syscon bindings so that it can be referenced from
the thermal node via a phandle.
