This doesn't seem like a great idea, driver name should not be made
ABI.

I would drop this patch and punt to the initrd. We need a more
flexible way to manage driver auto binding for CC under initrd control
anyhow, the same should be reused for hypervisors to shift driver
binding policy to userspace.
