dt-bindings: clock: mediatek: Drop duplicate mediatek,mt6795-sys-cloc…

…k.yaml

The compatible strings for mt6795 clocks are also documented in other
schemas:

"mediatek,mt6795-apmixedsys" in clock/mediatek,apmixedsys.yaml
"mediatek,mt6795-topckgen" in clock/mediatek,topckgen.yaml
"mediatek,mt6795-pericfg" in clock/mediatek,pericfg.yaml
"mediatek,mt6795-infracfg" in clock/mediatek,infracfg.yaml

The only difference is #reset-cells is not allowed in some of these,
but that aligns with actual users in .dts files.
