KVM: arm64: gic-v5: Add KVM_VGIC_V5_ADDR_TYPE_IRS to UAPI
Define the UAPI address type used by userspace to describe the
location of the emulated IRS in guest physical address space, together
with the size reserved for that region.
As per the GICv5 specification, the IRS has one CONFIG_FRAME and
optionally one SETLPI_FRAME per interrupt domain. Within a KVM VM we
are only concerned with one interrupt domain. Each of these frames is
64kB in size, so reserve 2x64kB of contiguous memory in the GPA space
for a GICv5 IRS.
