Dp_intf supports YUV422 as output format. In MT8195 Chrome project, YUV422 output format is used for 4K resolution.
Move this patch before [1]. Otherwise, [1] would result in a bug.
[1] [v12,10/14] drm/mediatek: dpi: Add dpintf support
ok, I will do this.

I will drop output format of MEDIA_BUS_FMT_YUV8_1X24 for mt8195_dpintf because if support MEDIA_BUS_FMT_YUV8_1X24 means support RGB888.
