dt-bindings: clock: qcom,sm8450-camcc: Move sc8280xp camcc to sa8775p camcc

SC8280XP camcc only requires the MMCX power domain, unlike SM8450 camcc
which now supports both MMCX and MXC power domains. Hence move SC8280XP
camcc from SM8450 to SA8775P camcc, to have single power domain support.

SA8775P camcc doesn't support required-opps property currently but SC8280XP
camcc need that property,  so add required-opps based on SC8280XP camcc
conditional check in SA8775P camcc bindings.
