UAPI Changes:

- Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709"

  The intent of Wa_14015141709 was to inform us that userspace can no
  longer control object-level preemption as it has on past platforms
  (i.e., by twiddling register bit CS_CHICKEN1[0]).  The description of
  the workaround in the spec wasn't terribly well-written, and when we
  requested clarification from the hardware teams we were told that on the
  kernel side we should also probably stop setting
  FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the
  hardware to honor the settings in per-context register CS_CHICKEN1.  It
  turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a
  mistake; even though CS_CHICKEN1[0] is non-operational and useless to
  userspace, there are other bits in the register that do still work and
  might need to be adjusted by userspace in the future (e.g., to implement
  other workarounds that show up).  If we don't set
  FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would
  not take effect.

      drm/i915/uc: Add patch level version number support · 65332a5b
      John Harrison authored 
      With the move to un-versioned filenames, it becomes more difficult to
know exactly what version of a given firmware is being used. So add
the patch level version number to the debugfs output.

Also, support matching by patch level when selecting code paths for
firmware compatibility. While a patch level change cannot be backwards
breaking, it is potentially possible that a new feature only works
from a given patch level onwards (even though it was theoretically
added in an earlier version that bumped the major or minor version).

      drm/i915/uc: Support for version reduced and multiple firmware files · 665ae9c9
      John Harrison authored 
      There was a misunderstanding in how firmware file compatibility should
be managed within i915. This has been clarified as:
  i915 must support all existing firmware releases forever
  new minor firmware releases should replace prior versions
  only backwards compatibility breaking releases should be a new file

This patch cleans up the single fallback file support that was added
as a quick fix emergency effort. That is now removed in preference to
supporting arbitrary numbers of firmware files per platform.

The patch also adds support for having GuC firmware files that are
named by major version only (because the major version indicates
backwards breaking changes that affect the KMD) and for having HuC
firmware files with no version number at all (because the KMD has no
interface requirements with the HuC).

For GuC, the driver will report via dmesg if the found file is older than
expected. For HuC, the KMD will no longer require updating for any new
HuC release so will not be able to report what the latest expected
version is.

      drm/qxl: fix the suspend/resume issue on qxl device · 4da7aad4
      Zongmin Zhou authored 
      Details:
Currently, when trying to suspend and resume with qxl device，
there are some error messages after resuming,
eventually caused to black screen and can't be recovered.

The first error message:
	[   64.668577][    C3] [drm] driver is in bug mode

This error is due to guest qxl driver
will call qxl_reinit_memslots(qdev) during system resume,
but didn't call qxl_io_reset(qdev) before this,
Then will cause the QXL_IO_MEMSLOT_ADD operation to fail on QEMU,
qxl->guest_bug flag will be set，As a result,
the QXL device can't communicate with guest qxl driver through the IO port.

after fix the first error,can success to resume and login to desktop,
but shortly after that will observe the second error message :
	[  353.095343][  T863] qxl 0000:00:02.0: object_init failed for (262144, 0x00000001)
	[  353.096660][  T863] [drm:qxl_gem_object_create [qxl]] *ERROR* Failed to allocate GEM object (260852, 1, 4096, -12)
	[  353.097277][  T863] [drm:qxl_alloc_ioctl [qxl]] *ERROR* qxl_alloc_ioctl: failed to create gem ret=-12
	[  368.197538][  T863] qxl 0000:00:02.0: object_init failed for (3149824, 0x00000001)
	[  368.197541][  T863] [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO

The problem is caused by calling qxl_ring_init_hdr(qdev->release_ring)
in qxl_drm_resume() function.
When do QXL_IO_RESET,QEMU will call init_qxl_ram(),
so params like prod,cons,notify_on_cons and notify_on_prod
will be set to default value.
Ring push/pop actions for release_ring can be performed normally.
But call qxl_ring_init_hdr(qdev->release_ring)
will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE,
affect the value of notify in qxl_push_free_res() function always be false,
QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the
guest qxl driver，so qxl_ring_pop() will never been called anymore，
and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx)
always return EBUSY,fail to call qxl_bo_create().

Test scenario:
1) start virtual machine with qemu command "-device qxl-vga"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in kernel logs,screen will be black

Let's fix this by reset io and remove the qxl_ring_init_hdr calling.
