drm/i915: Compartmentalize i915_gem_suspend/restore_gtt_mappings

Browse Source 
Having made start to better code compartmentalization by introducing
struct intel_gt, continue the theme elsewhere in code by making functions
take parameters take what logically makes most sense for them instead of
the global struct drm_i915_private.
