intel: Disable loading drivers on DG1 devices for now 

Kernel support for DG1 has not yet been merged upstream; per our
long-standing DRM subsystem policy, we should not enable the platform
in userspace until the kernel patches are merged and functional.

We will re-enable this in the future.  In the meantime, we retain all
of the infrastructure and code for the platform so that we can continue
developing DG1 support in upstream.
