dt/bindings: clk: fsl,plldig: Drop 'bindings' from schema id

Having 'bindings' in here causes a warning when checking the schema.

 Documentation/devicetree/bindings/clock/fsl,plldig.yaml:
 $id: relative path/filename doesn't match actual path or filename
         expected: http://devicetree.org/schemas/clock/fsl,plldig.yaml#



Remove it.
