re-write scatter gather memory allocation yet again...

This time, abandon the use of busdma and start interacting with the VM
system directly.  Make use of the new kmem_alloc_attr() which allows us
to easily allocate non-contiguous pages to back the GART table.  This
should help a lot when starting or restarting X after the system has
been running for a while and memory has become fragmented.

MFC after:	2 weeks
