powerpc: Remove irq_host_ops->remap hook
It was called from irq_create_mapping if that was called for a host and hwirq that was previously mapped, "to update the flags". But the only implementation was in beat_interrupt and all it did was repeat a hypervisor call without error checking that was performed with error checking at the beginning of the map hook. In addition, the comment on the beat remap hook says it will only called once for a given mapping, which would apply to map not remap. All flags should be known by the time the match hook is called, before we call the map hook. Removing this mostly unused hook will simpify the requirements of irq_domain concept.
