drm/i915: Fix AVI/HDMI/SPD infoframes on HSW+

I broke AVI/HDMI/SPD infoframes on HSW+ with the register type
safety changes. We were supposed to check that the infoframe data
register is valid before writing the infoframe data, but the check
ended up inverted, and so in practice we never wrote or enabled
these infoframes.

We were still sending out the GCP infoframe when the sink was
deep-color capable. That and the fact that we use a single
bool to track our infoframe state meant that the state checker
only caught this when a HDMI sink that doesn't do deep-color was
used.

We really need to fix our infoframe state checking to be much
more anal. But in the meantime let's just fix the regression.
In fact let's just throw out the register validity check and
convert some of the "unknown info frame type" debug messages
into MISSING_CASE(). So far we support the same set of infoframe
types on all platforms, so the silent debug messages make no
sense.
