A series to fix and add xe support for AuxCSS framebuffers via DPT.

Currently the auxiliary buffer data isn't mapped into the page tables at all so
cf48bddd31de ("drm/i915/display: Disable AuxCCS framebuffers if built for Xe")
had to disable the support.

On top of that there are missing flushes, invalidations and similar.

Tested with KDE Wayland, on Lenovo Carbon X1 ADL-P:

  [PLANE:32:plane 1A]: type=PRI
          uapi: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=visible, src=2880.000000x1800.000000+0.000000+0.000000, dst=2880x1800+0+0, rotation=0 (0x00000001)
          hw: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=yes, src=2880.000000x1800.000000+0.000000+0.000000, dst=2880x1800+0+0, rotation=0 (0x00000001)

Display working fine - no artefacts, no DMAR/PIPE faults.

All IGTs pass for me locally.

v2:
 * More patches added to fix kms_flip_tiling.

v3:
 * Rebased after some cleanup patches from v2 were merged.
 * Added people to Cc as suggested by Rodrigo.
 * Adjusted last patch title. (Rodrigo)
 * Apply GGTT flushing only to iomapped system memory buffers.

v4:
 * Added patch for potentially misplaced Wa_14016712196.
 * Fixed (hopefully) MAX_JOB_SIZE_DW on Meteorlake.

v5:
 * Split out ring emission changes to smaller patches.
 * Fixed MAX_JOB_SIZE_DW even more.
 * Don't emit MI_FLUSH_DW_CCS on !BCS. This should fix Meteorlake.

 v6:
 * Added AuxCCS invalidation to indirect context workarounds.
 * Also added the indirect context handling and some other workarounds. They are
   unrelated but the series depends on it.
 * Dropped DPT pin alignment reduction since BMG appears not to be liking it for
   some reason.

v7:
 * Rebased on top of recent xe_fb_pin.c refactoring and also the indirect
   context workarounds series.

v8:
 * Rebased for bo->size removal.
 * Corrected PIPE_CONTROL_FLUSH_L3 to bit 30. (Jose)

v9:
 * Fixed fb remapping changes.
 * Dropped two not required patches from the series.
 * Fixed criteria for GGTT flushing.
 * Limit clflush to the compression metadata area.
 * Rebased for indirect context workarounds landing upstream.

v10:
 * Rebase for XE_GT_WA().

v11:
 * Do not use stolen for DPT on IGFX + AuxCCS.

v12:
 * Rebased for some ringbuf and LRC code changes.

v13:
 * Rebased for various upstream changes.
 * Dropped clflush and stolen avoidance patches after merging IGT MOCS 61 usage.
