See discussion for v2 of this patch. I suggested that drivers/firmware and virt/
as options, the counterarguments were that drivers/firmware is for passive
firmware as opposed to firmware that acts as a hypervisor, and that virt/ is
for the host side of hypervisors like kvm, not for guests.

The driver in here most closely resembles the xen dom0 model, where a
priviledged guest controls other guests, but unlike xen there is a single
driver file, so there is no need to have drivers/fsl-hv directory just
for this one file. We do have a number of other hypervisors that fit in the
same category, so they can be added here later.
