i965: Cite the 965 PRM for "the data cache is the sampler cache".
Presumably, this comment exists to justify the usage of
I915_GEM_DOMAIN_SAMPLER for this relocation. At one point, this was
necessary to ensure that the right flushing was done to keep caches
coherent. These days, the kernel just flushes everything, so I don't
think it matters.
Still, the comment is interesting, so leave it in place.
