Douglas Anderson baef4d5619 drm/bridge: ti-sn65dsi86: Clear old error bits before AUX transfers 
The AUX channel transfer error bits in the status register are latched
and need to be cleared.  Clear them before doing our transfer so we
don't see old bits and get confused.

Without this patch having a single failure would mean that all future
transfers would look like they failed.
