The GIC is available for more than just "virt". It's just that
at the moment "virt" is the only machine type which lets you
pick which GIC version you want, and so the only machine type
with that machine property. (For instance vexpress-a15
is always GICv2, since the hardware we're modelling there is
always GICv2.)

Other board models in future might support a choice of GIC
versions. (The obvious possibility would be the Android
'ranchu' board if that is ever upstreamed.)
