[PATCH] dt-bindings: display: mediatek: Compatible list cleanup

[Yassine Oudjana]

From: Yassine Oudjana <y.oudjana@xxxxxxxxxxxxxx>

Several DT bindings of MediaTek display blocks make unnecessary use of
"oneOf" and "items", and have some enums with only 1 element. Remove
unnecessary "oneOf" and "items", and replace enums that have 1 element
with "const".
