[Qemu-devel] [PULL 11/22] gus: clean up MemoryRegionPortio

[Paolo Bonzini <pbonzini@redhat.com>]

Remove 16-bit reads/writes, since ioport.c is able to synthesize them.
Remove the two MIDI registers (0x300 and 0x301) from gus_portio_list1,
and add the second MIDI register (0x301) to gus_portio_list2.

Tested with Second Reality.
