scsi: dt-bindings: mediatek,ufs: add MT8195 compatible and update clock nodes 



Add MT8195 UFSHCI compatible string.  Relax the schema to allow between
one to eight clocks/clock-names entries for all MediaTek UFS
nodes. Legacy platforms may only need a few clocks, whereas newer devices
such as the MT8195 require additional clock-gating domains. For MT8195
specifically, enforce exactly eight clocks and clock-names entries to
satisfy its hardware requirements.
