xen: allow disabling PV disks and nics
Introduce two new loader tunnables that can be used to disable PV disks and PV nics at boot time. They default to 0 and should be set to 1 (or any number different than 0) in order to disable the PV devices: hw.xen.disable_pv_disks=1 hw.xen.disable_pv_nics=1 In /boot/loader.conf will disable both PV disks and nics.
