[why]
dcn301_calculate_wm_and_dl() causes flickering when external monitor is
connected.

This issue has been fixed before by commit 0e4c0ae5
("drm/amdgpu/display: drop dcn301_calculate_wm_and_dl for now"), however
part of the fix was gone after commit 2cbcb78c ("Merge tag 'amd-drm-next-5.13-2021-03-23' of https://gitlab.freedesktop.org/agd5f/linux into drm-next").

[how]
Use dcn30_calculate_wm_and_dlg() instead as in the original fix.

Long ago, there had been plans for making use of a bunch of these APIs
from userspace and there's various checks in place to stop misbehaving.

Countless other projects have occurred in the meantime, and the pieces
didn't finish falling into place for that to happen.

They will (hopefully) in the not-too-distant future, but it won't look
quite as insane.  The super checks are causing problems right now, and
are going to be removed.

Reviewed-by: Lyude Paul <lyude@redhat.com>

When booted with multiple displays attached, the EFI GOP driver on (at
least) Ampere, can leave DP links powered up that aren't being used to
display anything.  This confuses our tracking of SOR routing, with the
likely result being a failed modeset and display engine hang.

Fix this by (ab?)using the DisableLT IED script to power-down the link,

[Why]
Userspace should get back a copy of drm_wait_vblank that's been modified
even when drm_wait_vblank_ioctl returns a failure.

Rationale:
drm_wait_vblank_ioctl modifies the request and expects the user to read
it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates
the sequence to become current_vblank_count + sequence (which was
RELATIVE), but now it became ABSOLUTE.
drmWaitVBlank (in libdrm) expects this to be the case as it modifies
the request to be Absolute so it expects the sequence to would have been
updated.

The change is in compat_drm_wait_vblank, which is called by
drm_compat_ioctl. This change of copying the data back regardless of the
return number makes it en par with drm_ioctl, which always copies the
data before returning.

[How]
Return from the function after everything has been copied to user.

In 69de4421 ("drm/ttm: Initialize debugfs from
ttm_global_init()"), ttm_global_init was changed so that if creation
of the debugfs global root directory fails, ttm_global_init will bail
out early and return an error, leading to initialization failure of
DRM drivers. However, not every system will be using debugfs. On such
a system, debugfs directory creation can be expected to fail, but DRM
drivers must still be usable. This changes it so that if creation of
TTM's debugfs root directory fails, then no biggie: keep calm and
carry on.
