target-arm: Add virt machine secure property
Add "secure" virt machine specific property to allow override of the
default secure state configuration. By default, when using the QEMU
-kernel command line argument, virt machines boot into NS/SVC. When using
the QEMU -bios command line argument, virt machines boot into S/SVC.
The secure state can be changed from the default specifying the secure
state as a machine property. For example, the below command line would disable
security extensions on a -kernel Linux boot:
aarch64-softmmu/qemu-system-aarch64
-machine type=virt,secure=off
-kernel ...
