Instead of the GIC virtual CPU interface an emulated GICv3 needs to have accesses to its emulated redistributors trapped in the guest. Add code to tell the kernel about the mapping if a GICv3 emulation was requested by the user. This contains some defines which are not (yet) in the (32 bit) header files to allow compilation for ARM.
