i965: Allocate VMA in userspace for full-PPGTT systems.
This patch enables soft-pinning of all buffers, allowing us to skip
relocation processing entirely. All systems with full PPGTT and > 4GB
of VMA should gain these benefits. This should be most Gen8+.
Unfortunately, this excludes a few systems:
- Cherryview (only has 32-bit addressing, despite 48-bit pointers)
- Broadwell with a 32-bit kernel
- Anybody running pre-4.5 kernel.
We may enable it for Cherryview in the future, but it would require
some tweaks to the memory zone.
