[PATCH v2] dt-bindings: display: mediatek: mutex: remove power-domain from requird

["jason-jh.lin" <jason-jh.lin@xxxxxxxxxxxx>]

There is no power control in mutex driver, so power-domain
is not the required property.

Fixes: 4ed545e7d100 ("dt-bindings: display: mediatek: disp: split each block to individual yaml")
Signed-off-by: jason-jh.lin <jason-jh.lin@xxxxxxxxxxxx>
