hw/pci-host/q35: Inline sysbus_add_io()
sysbus_add_io() just wraps memory_region_add_subregion() while also obscuring where the memory is attached. So use memory_region_add_subregion() directly and attach it to the existing memory region s->mch.address_space_io which is set as an alias to get_system_io() by the q35 machine.
