On platforms/outputs without a working frame counter we rely
on the vblank code to cook up the frame counter from the timestamps.
That requires that vblank support is enabled. Thus we need to
move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.
The alternative would be to give up on having the frame counter
values in the trace which would render the tracepoints more or
less pointless.

Populate conn_state->max_bpc with something sensible from the start.
Otherwise it's possible that we get to compute_sink_pipe_bpp() with
max_bpc==0.
The specific scenario goes as follows:
1. Initial connector state allocated with max_bpc==0
2. Trigger a modeset on the crtc feeding the connector, without
actually adding the connector to the commit
3. drm_atomic_connector_check() is skipped because the
connector has not yet been added, hence conn_state->max_bpc
retains its current value
4. drm_atomic_helper_check_modeset() ->
drm_atomic_add_affected_connectors() -> the connector
is now part of the commit
5. compute_baseline_pipe_bpp() -> MISSING_CASE(max_bpc==0)
Note that pipe_bpp itself may not be populated on pre-g4x machines,
in which case we just fall back to max_bpc==8 and let .compute_config()
limit the resulting pipe_bpp further if necessary.

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

intel_gt_driver_register() may be called earlier than
intel_opregion_register() and acpi_video_register(), so move it up.
intel_display_debugfs_register() may be called later, together with the
other display-related initializations. There is a slight change in
behavior that sysfs files will show up before the display-related
debugfs files, but that shouldn't be a problem - userspace shouldn't be
relying in debugfs.
This allows us to group all the display-related calls under a single
check for "HAS_DISPLAY()" that can be later moved to a better place.
