[PATCH v4 00/16] drm/i915: (stolen) memory region related fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Attempt to fix the mess around stolen memory, especially on MTL
with it's special (and apparenly broken) not-actually-lmem stolen.

The series is made up of roughtly three parts:
1. General refactoring/debug improvement for mem regions
2. Deal with the broken BAR stuff on MTL
3. Fix initial display plane readout for MTL

v2: Try to relocate the BIOS fb to start of ggtt to make
    space for the GuC stuff at the top end of ggtt
v3: Skip ton VM guests as they won't have access to stolen directly
    Annotate more initial fb takeover failure paths
    Add the w/a numbers
v4: Check the magic pcode bit
    Try to deal with xe fallout
