drm/i915/vlv: DPI FIFO empty check is not needed
While sending DPI SHUTDOWN command, we cannot wait for FIFO empty as pipes are not disabled at that time. In case of MIPI we disable port first and send SHUTDOWN command while pipe is still running and FIFOs will not be empty, causing spurious error log Signed-off-by: Shobhit Kumar <shobhit.kumar@intel.com> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
