exec/ioport: Add portio_list_set_enabled()
Some SuperI/O devices such as the VIA south bridges or the PC87312 controller
allow to enable or disable their SuperI/O functions. Add a convenience function
for implementing this in the VIA south bridges.
The naming of the functions is inspired by its memory_region_set_enabled()
pendant.
