[PATCH v2 1/6] drm/mediatek: Remove mt8192 display rdma compatible

[Allen-KH Cheng <allen-kh.cheng@mediatek.com>]

The compatible “mediatek,mt8192-disp-rdma” is being used for reading
the data into DMA for back-end panel driver in mt8192 but there is
no difference between mt8183 and mt8192 in rdma driver.

Remove compatible “mediatek,mt8192-disp-rdma” from the driver and
should use “mediatek,mt8183-disp-rdma” as fallback in 8192 DTS
according to the mediatek,rdma.yaml.
