On XEHP platforms user is not able to find MMIO triggered reports in the
OA buffer since i915 squashes the context ID fields. These context ID
fields hold the MMIO trigger markers.

Update logic to not squash the context ID fields of MMIO triggered
reports.

intel_wakeref_t is supposed to be a mostly opaque cookie to its
users. It should only be checked for being non-zero and set to
zero. Debug logging its actual value is meaningless. Switch to just
debug logging whether the async_put_wakeref is non-zero.

The issue dates back to much earlier than
commit b49e894c ("drm/i915: Replace custom intel runtime_pm tracker

MST connectors don't have a static attached encoder, as their encoder
can change depending on the pipe they use; so the encoder for an MST
connector can't be retrieved using intel_dp_attached_encoder() (which
may return NULL for MST). Most of the PSR debugfs entries depend on a
static connector -> encoder mapping which is only true for eDP and SST
DP connectors and not for MST. These debugfs entries were enabled for
MST connectors as well recently to provide PR information for them, but
handling MST connectors needs more changes.

Fix this by not adding for now the PSR entries on MST connectors. To
make things more uniform add the entries for SST connectors on all
platforms, not just on platforms supporting DP2.0.

v2:
- Keep adding the entries for SST connectors. (Jouni)
- Add a TODO: comment for MST support.

IGT `amdgpu/amd_color/crtc-lut-accuracy` fails right at the beginning of
the test execution, during atomic check, because DC rejects the
bandwidth state for a fb sizing 64x64. The test was previously working
with the deprecated dc_commit_state(). Now using
dc_validate_with_context() approach, the atomic check needs to perform a
full state validation. Therefore, set fast_validation to false in the
dc_validate_global_state call for atomic check.

The check for sending the vsc infopacket to the display was gated behind
PSR (Panel Self Refresh) being enabled.

The vsc infopacket also contains the colorimetry (specifically the
container color gamut) information for the stream on modern DP.

PSR is typically only supported on mobile phone eDP displays, thus this
was not getting sent for typical desktop monitors or TV screens.

This functionality is needed for proper HDR10 functionality on DP as it
wants BT2020 RGB/YCbCr for the container color space.
