- Call drm_connector_update_privacy_screen() from

fd2b94a5cb drm/i915/trace: split out display trace to a separate file 
Add display/intel_display_trace.[ch] for defining display
tracepoints. The main goal is to reduce cross-includes between gem and
display. It would be possible split up tracing even further, but that
would lead to more boilerplate.

We end up having to include intel_crtc.h in a few places because it was
pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and
that's no longer the case.

There should be no changes to tracepoints.

v3:
- Rebase

v2:
- Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris)
- Remove useless comments (Ville)

    DDI TC1->ddc_pin=3 should translate to PORT_TC1->0x9

    DDI TC3->ddc_pin=5 should translate to PORT_TC3->0xb
    DDI TC4->ddc_pin=6 should translate to PORT_TC4->0xc

Adding pin map to facilitate this translation as we cannot use existing
icl ddc pin map due to conflict with DDI C and DDI TC1 info.

and later checks then prevent it from being reactivated. We
can simpify our lives a bit by logically disabling FBC on

FBC is logically enabled but can't actually be activated.

32024bb85e drm/i915/fbc: Pass i915 instead of FBC instance to FBC underrun stuff 
The underrun code doesn't need to know any details about FBC, so
just pass in the whole device rather than a specific FBC instance.
We could make this a bit more fine grained by also passing in the
pipe to intel_fbc_handle_fifo_underrun_irq() and letting the FBC
code figure which FBC instance (if any) is active on said pipe.
But that seems a bit overkill for this so don't bother.
