[PATCH 04/12] drm/i915: Convert pipe_config_infoframe_mismatch() to drm_printer

[Ville Syrjala <ville.syrjala@xxxxxxxxxxxxxxx>]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Utilize drm_printer in pipe_config_infoframe_mismatch() to avoid
a bit of code duplication.

hdmi_infoframe_log() can't use the printer of course, but for that
we can just figure out which loglevel to use. And we do need to keep
the explicit drm_debug_enabled(DRM_UT_KMS) since hdmi_infoframe_log()
won't do it for us.
