Subject: [PATCH v4 5/8] dt-bindings: ufs: mediatek,ufs: Document MT8192 compatible with MT8183

The MT8192 UFS controller is compatible with the MT8183 one:
document this by allowing to assign both compatible strings
"mediatek,mt8192-ufshci", "mediatek,mt8183-ufshci" to the UFSHCI node.

Moreover, since no MT8192 devicetree ever declared any UFSHCI node,
disallow specifying only the MT8192 compatible.

In preparation for adding MT8195 to the mix, the MT8192 compatible
was added as enum instead of const.

Also, while at it, replace Stanley Chu with me in the maintainers
field, as he is unreachable and his email isn't active anymore.
