Add three properties for MT8196 settings: - 'mediatek,prohibit-gate-cg', indicate if the source clock CG could be disabled when CPU access IP registers. - 'mediatek,stop-dly-sel', configure read data clock stops at block gap. - 'mediatek,pop-en-cnt', configure the margins of write and read pointers while begin to pop data transfer.
