This adds a hypervisor command line option "hardware_dom=" which takes a
domain ID. When the domain with this ID is created, it will be used
as the hardware domain.
This is intended to be used when domain 0 is a dedicated stub domain for
domain building, allowing the hardware domain to be de-privileged and
act only as a driver domain.
