A bunch of fixes to avoid null pointer dereference in fbcon, fix a return

and a conflicting framebuffer in vboxvideo.

drm-misc-fixes for v5.6:
- SG fixes for prime, radeon and amdgpu.

Two main topics in that first drm-misc-next-fixes PR, first a revert of the
data-mapping property in the DT that turned out to be non-optimal (but
hasn't reached a stable release yet), and an improvement of a Kconfig help
text.

One more fix for v5.6:
- drm/lease: fix WARNING in idr_destroy

  workaround firmware fb.

drm-misc-next for 5.7:

UAPI Changes:

Cross-subsystem Changes:

Core Changes:
  - dp-mst: Remove register_connector callback, add drm_dp_destroy_connector
  - Changes to scnprintf on multiple instances

Driver Changes:
  - meson: Support for YUV420
  - panel: Support Ortustech COM37H3M, idk-1110wr and idk-2121wr,
           multiple dotclock fixes

UAPI Changes: None

Cross-subsystem Changes: None

Core Changes: Fixed regressions introduced by commit cd82d82cbc04
("drm/dp_mst: Add branch bandwidth validation to MST atomic check"),
which would cause us to:

* Calculate the available bandwidth on an MST topology incorrectly, and
  as a result reject most display configurations that would try to enable
  more then one sink on a topology
* Occasionally expose MST connectors to userspace before finishing
  probing their PBN capabilities, resulting in us rejecting display
  configurations because we assumed briefly that no bandwidth was
  available

Driver Changes: None

UAPI Changes: None

Cross-subsystem Changes: None

Core Changes: Fixed some issues introduced by commit cd82d82cbc04
("drm/dp_mst: Add branch bandwidth validation to MST atomic check"),
which caused the DP MST helpers to incorrectly reject display
configurations in drm_dp_mst_atomic_check() as a result of
miscalculating the available bandwidth. Additionally, another issue that
was required for this to work was fixed where we would reject display
configurations because we would accidentally expose MST connectors to
userspace before having probed their available bandwidth.

Driver Changes: None

UAPI Changes: None

Cross-subsystem Changes: None

Core Changes: Re-write the bandwidth helper checks in
drm_dp_mst_atomic_check() to fix some regressions that were introduced
by commit cd82d82cbc04 ("drm/dp_mst: Add branch bandwidth validation to
MST atomic check"). This was put into a topic branch per-request of
airlied.

Driver Changes: None
