drm/omap: dsi: fix DCS_CMD_ENABLE 



We only need to set VC_CTRL:DCS_CMD_ENABLE for command mode panels when
the HW has DSI_QUIRK_DCS_CMD_CONFIG_VC quirk. The old code did this
right by accident, but now we set DCS_CMD_ENABLE for video mode panels
too.

Fix this by skipping the set for video mode.
