[Intel-gfx] [PULL] drm-intel-fixes

[Tvrtko Ursulin]

Hi Dave, Daniel,

A few fixes for 6.1.

On the display side fixed a race condition in accessing DKL PHY registers
(TGL+), fixed LVDS EDID fixed mode setup and fixed SDVO invalid mode
filtering. On the GEM side fix running under Xen and use DMA API directly
instead of special casing for SWIOTLB only.

drm-intel-fixes-2022-11-03:
- Add locking around DKL PHY register accesses (Imre Deak)
- Stop abusing swiotlb_max_segment (Robert Beckett)
- Filter out invalid outputs more sensibly (Ville Syrjälä)
- Setup DDC fully before output init (Ville Syrjälä)
- Simplify intel_panel_add_edid_alt_fixed_modes() (Ville Syrjälä)
- Grab mode_config.mutex during LVDS init to avoid WARNs (Ville Syrjälä)
