We cannot use multiple reset lines at the same time. - Invalidate mediatek,mcm if the compatible device is mediatek,mt7531. There is no multi-chip module version of mediatek,mt7531. - Require mediatek,mcm for mediatek,mt7621 as the compatible string is only used for the multi-chip module version of MT7530.
