drm/i915/uc: Reserve upper range of GGTT
GuC and HuC depend on struct_mutex for device reinitialization. Moving
away from this dependency requires perma-pinning the firmware images in
GGTT. The upper portion of the GuC address space has a sizeable hole
(several MB) that is inaccessible by GuC. Reserve this range within GGTT
as it can comfortably hold GuC/HuC firmware images.
v2: Reserve node rather than insert (Chris)
Simpler determination of node start/size (Daniele)
Move reserve/release out to intel_guc.* files
v3: Reserve starting at GUC_GGTT_TOP only and bail if this
fails (Chris)
