I'm fine with exporting by default, but just loading won't really work
even with that:

- there are a bunch of IS_ENABLED conditionals in the i915 (although
they look like minor optimizations to me).
- the enable_gvt needs to be set, although after this refactor this
option is completely pointless and should probably be enabled
- the enable_guc option needs to be disable for gvt to work.
