drm/i915: Check infoframe state in intel_pipe_config_compare()
Check the infoframes and infoframe enable state when comparing two
crtc states.
We'll use the infoframe logging functions from video/hdmi.c to
show the infoframes as part of the state dump.
TODO: Try to better integrate the infoframe dumps with
drm state dumps
v2: drm_printk() is no more
