drm/i915: document caching related bits
Try to document the object caching related bits, like cache_coherent and
cache_dirty.
v2(Ville):
- As pointed out by Ville, fix the completely incorrect assumptions
about the "partial" coherency on shared LLC platforms.
v3(Daniel):
- Fix nonsense about "dirtying" the cache with reads.
v4(Daniel):
- Various improvements, including adding some more details for WT.
