[PATCH 2/2] soc: mediatek: mutex: Add support for MT6795 Helio X10 display mutex

[AngeloGioacchino Del Regno]

MT6795 has the same mutex mod/sof register layout as MT2712 and MT8173,
but supports only four SOF, as it has two DSI and one DPI.
Support is added by reusing most of the MT8173 data, with the addition
of a mt6795-specific SOF array (and devicetree compatible, of course).
