arm/arm64: KVM: vgic: make number of irqs a configurable attribute
In order to make the number of interrupts configurable, use the new fancy device management API to add KVM_DEV_ARM_VGIC_GRP_NR_IRQS as a VGIC configurable attribute. Userspace can now specify the exact size of the GIC (by increments of 32 interrupts).
