drm/i915: Split out i915_vma.c
As a side product, had to split two other files; - i915_gem_fence_reg.h - i915_gem_object.h (only parts that needed immediate untanglement) I tried to move code in as big chunks as possible, to make review easier. i915_vma_compare was moved to a header temporarily. v2: - Use i915_gem_fence_reg.{c,h} v3: - Rebased v4: - Fix building when DEBUG_GEM is enabled by reordering a bit.
