Currently on x86 we can use either legacy +foo1,-foo2,foo3 and
in addition to it we ca use canonized format for generic properties
like, foo1=on,foo2=off,foo3=on

We try to move out of legacy format, so that it would be possible
to reuse generic property parsing infrastructure like with any
device object. That would allow to use -device/device_add for CPUs.
