drm/i915: Use VMA as the primary object for context state
When working with contexts, we most frequently want the GGTT VMA for the
context state, first and foremost. Since the object is available via the
VMA, we need only then store the VMA.
v2: Formatting tweaks to debugfs output, restored some comments removed
in the next patch
