hw/intc/arm_gic: Add Security Extensions property
Add a QOM property which allows the GIC Security Extensions to be enabled. These are an optional part of the GICv1 and GICv2 architecture. This commit just adds the property and some sanity checks that it is only enabled on GIC revisions that support it.
