[PATCH v2 1/2] dt-bindings: clock: loongson,ls2k: Add ls2k1000 compatible and deprecate legacy

[wjjsn <wjjsn@qq.com>]

Add a SoC-specific compatible string "loongson,ls2k1000-clk" for
Loongson-2K1000.

Mark the legacy "loongson,ls2k-clk" compatible as deprecated using
the structured "deprecated: true" property instead of relying on
textual description.

Update the example to use the new compatible.
