ARM: KVM: VGIC accept vcpu and dist base addresses from user space
User space defines the model to emulate to a guest and should therefore decide which addresses are used for both the virtual CPU interface directly mapped in the guest physical address space and for the emulated distributor interface, which is mapped in software by the in-kernel VGIC support.
