[PATCH 2/3] dt-bindings: ufs: mediatek,ufs: add MT8195 compatible and update clock nodes

[Macpaul Lin <macpaul.lin@mediatek.com>]

Add 'mediatek,mt8195-ufshci' to compatible list.
Update clocks and clock-names constraints to allow one to eight entries.
Introduce 'mediatek,ufs-disable-mcq' property to disable
MCQ (Multi-Circular Queue). Update conditional schema for mt8195
requiring eight 'clocks' and eight 'clock-names'.
