After some offline discussion with Jason and Pasha, I will drop this
patch from the next version to avoid hard-coding a policy in the kernel.

Instead, for the time being, it will be the user's responsibility to
only preserve devices that do not have any built-in drivers that will
bind to the device during boot following a Live Update.
