drm/i915: kerneldoc for i915_gem_shrinker.c
And remove one bogus * from i915_gem_gtt.c since that's not a kerneldoc there. v2: Review from Chris: - Clarify memory space to better distinguish from address space. - Add note that shrink doesn't guarantee the freed memory and that users must fall back to shrink_all. - Explain how pinning ties in with eviction/shrinker.
