OMAP: DSS2: DSI: sync when disabling a display
When the panel driver calls omapdss_dsi_display_disable() it is possible
that there are still some unsent packets in the TX fifo.
Add dsi_sync_vc() calls in the beginning of
omapdss_dsi_display_disable() to make sure the TX fifos are empty.
This allows us to remove the msleep(10) hack from panel-taal.c
