[PULL] drm-intel-fixes

[Jani Nikula]

Hi Dave & Daniel -

Due to issues in s2idle in v5.6-rc2, I've gotten CI results on these
with two hack reverts on top, and I threw them out just before making
the pull request. I had to revert:

fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system")
e3728b50cd9b ("ACPI: PM: s2idle: Avoid possible race related to the EC GPE")

I've been told the issues have been reported, hopefully we'll get the
fixes in Linus' upstream soon too.

drm/i915 fixes for v5.6-rc3:
- Workaround missing Display Stream Compression (DSC) state readout by
  forcing modeset when its enabled at probe
- Fix EHL port clock voltage level requirements
- Fix queuing retire workers on the virtual engine
- Fix use of partially initialized waiters
- Stop using drm_pci_alloc/drm_pci/free
- Fix rewind of RING_TAIL by forcing a context reload
- Fix locking on resetting ring->head
- Propagate our bug filing URL change to stable kernels

BR,
Jani.
