The commit c87d1c4b5b9a ("drm/mediatek: dsi: Use symbolized register definition") inverted the logic of the control bit. Maybe it was because of the bad naming which was fixed in commit 0f3b68b66a6d ("drm/dsi: Add _NO_ to MIPI_DSI_* flags disabling features"). In any case, the logic wrong and there will be no EOTp on the DSI link by default. Fix it.
