drm/i915: Nuke INTEL_OUTPUT_FORMAT_INVALID
We tend to use output_format!=RGB as a shorthand for YCbCr, but
this fails if we have a disabled crtc where output_format==INVALID.
We're now getting some fail from intel_color_check() when we have:
hw.enable==false
hw.ctm!=NULL
output_format==INVALID
Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the
dumpster, and thus everything defaults to RGB when the crtc
is disabled.
This does beg the deeper question of how much of the state
should we in fact be validating when hw/uapi.enable==false.
And should we even be doing the uapi->hw copy when
uapi.enable==false? So far I've not been able to come up with
satisfactory answers for myself, so I'm putting it off for the
moment.
