Subject: [PATCH 3/3] drm/bridge: ti-sn65dsi86: correct dsi mode_flags

From: Rob Clark <robdclark@...omium.org>

Noticed while comparing register dump of how bootloader configures DSI
vs how kernel configures.  It seems the bridge still works either way,
but fixing this clears the 'CHA_DATATYPE_ERR' error status bit.
