Why are we making the UI for "enable EL2 guest with KVM" different
from that for "enable EL2 guest with TCG" ? Currently an EL2
TCG guest is set up with "-M virt,virtualization=on", which then
does everything it needs to enable virtualization on all the
components on the board including the CPU.
Unless there's a strong technical reason why KVM EL2 has to
be different, I think we should use the same switch.
