KVM: arm/arm64: arch_timer: Remove irq_phys_map
Now that the interface between the arch timer and the VGIC does not require passing the irq_phys_map entry pointer anymore, let's remove it from the virtual arch timer and use the virtual IRQ number instead directly. The remaining pointer returned by kvm_vgic_map_phys_irq() will be removed in the following patch.
