drm/i915: Make contexts non-snooped on non-LLC platforms
We don't do CPU access to GPU contexts so making the GPU access snoop
the CPU caches seems silly, and potentially expensive.
v2: Use !IS_VALLEYVIEW instead of HAS_LLC as this is really
about what the PTEs can represent.
Add a comment clarifying the situation.
