q800: reimplement mac-io region aliasing using IO memory region
The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".
Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.
