The hotplugging and the tests currently in usb-hcd-ehci-test are quite
different.  Hotplugging creates a empty machine, then plugs + unplugs
stuff.  usb-hcd-ehci-test creates a machine with ehci+ohci companions,
then goes run a bunch of tests for it.

Maybe it makes sense to have a usb-hcd-hotplug-test.c file and collect
hotplug testing for all usb hcds we have there.  For code sharing
that'll be better for sure as the basic code flow is the same for all
hcd types.

cheers,
