dt-bindings: display: mediatek: split: add subschema property constraints 



The display node in mt8195.dtsi was triggering a CHECK_DTBS error due
to an excessively long 'clocks' property:
  display@14f06000: clocks: [[31, 14], [31, 43], [31, 44]] is too long

To resolve this issue, the constraints for 'clocks' and
other properties within the subschemas will be reinforced.
