This reverts commit 88b065943c.
Lenovo 82TQ is unhappy if we do the display on sequence this
late. The display output shows severe corruption.
It's unclear if this is a failure on our part (perhaps
something to do with sending commands in LP mode after HS
/video mode transmission has been started? Though the backlight
on command at least seems to work) or simply that there are
some commands in the sequence that are needed to be done
earlier (eg. could be some DSC init stuff?). If the latter
then I don't think the current Windows code would work
either, but maybe this was originally tested with an older
driver, who knows.
Root causing this fully would likely require a lot of
experimentation which isn't really feasible without direct
access to the machine, so let's just accept failure and
go back to the original sequence.

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.

Add pll selection check for C20 as well as
clock state verification0. We have been relying
on sw state to select A or B pll's. This is incorrect
as the hw might see this selection differently. This

for both sw and hw states and compares if these two
selections match.

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.
