[Intel-gfx] [PATCH 4/8] drm/i915/sdvo: Simplify output setup debugs

[Ville Syrjala]

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

Get rid of this funny byte based dumping of invalid output
flags and just dump it as a single hex numbers. Also do that
early since all the rest is going to get skipped anyway of
the thing is zero.
