i965: Move the remaining intel code to the i965 directory.
Now that i915's forked off, they don't need to live in a shared directory. Acked-by: Kenneth Graunke <kenneth@whitecape.org> Acked-by: Chad Versace <chad.versace@linux.intel.com> Acked-by: Adam Jackson <ajax@redhat.com> (and I hear second hand that idr is OK with it, too)
