Subject: [PATCH] drm/mediatek: Fix wrong dither settings

The width and height arguments in the cmdq packet for mtk_dither_config()
are inverted. We fix the incorrect width and height for dither settings
in mtk_dither_config().

Fixes: 73d3724745db ("drm/mediatek: Adjust to the alphabetic order for mediatek-drm")
