hw/sysbus: Inline and remove sysbus_add_io()

Browse source 
sysbus_add_io(...) is a simple wrapper to
memory_region_add_subregion(get_system_io(), ...).
It is used in 3 places; inline it directly.

Rationale: we want to move to an explicit I/O bus,
rather that an implicit one. Besides in heterogeneous
setup we can have more than one I/O bus.
