[PATCH 15/24] macio: Fix macio-bus to be a subtype of System bus

[Markus Armbruster]

The devices we plug into the macio-bus are all sysbus devices
(DeviceClass member bus_type is TYPE_SYSTEM_BUS), but macio-bus does
not derive from TYPE_SYSTEM_BUS.  Fix that.

"info qtree" now shows the devices' mmio ranges, as it should
