[PATCH v3 04/16] drm/msm/dpu: Stop copying around mode->private_flags

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The driver never sets mode->private_flags so copying
it back and forth is entirely pointless. Stop doing it.

Also drop private_flags from the tracepoint.
