Use the ttm handlers for servicing page faults, and vm_access. We do our own validation of read-only access, otherwise use the ttm handlers as much as possible. Because the ttm handlers expect the vma_node at vma->base, we slightly need to massage the mmap handlers to look at vma_node->driver_private to fetch the bo, if it's NULL, we assume i915's normal mmap_offset uapi is used. This is the easiest way to achieve compatibility without changing ttm's semantics.
