intel: Conditionally compile mcs-related code for i965 only.
This patch ifdefs out intel_mipmap_tree::mcs_mt when building the i915
(pre-Gen4) driver (MCS buffers aren't supported until Gen7, so there
is no need for this field in the i915 driver). This should make it a
bit easier to implement fast color clears without undue risk to i915.
