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.
Fixes: 739058a9c5c3 ("dt-bindings: display: mediatek: split: add compatible for MT8195")

Changes since v4:
- Eliminate the possibility of varying quantities in the 'clocks'
property of mt8195.
- Move the constraint for 'power-domains' to the top-level.
Changes since v3:
- Correct the compatible name for the mt8173 split in the subschema.
Changes since v2:
- Revise the commit message.
- Enhance the descriptions of 'clocks'.
