vaallocator: only i965 can switch derived/non-derived at mapping

Browse source 
Since newer drivers change the strides and offset, and they have to be defined
at allocation time because those parameters are stored in the GstVideoMeta in
the buffer pool.

Thinks patch is based on commit 6b1fba14 and commit 809a984b
