Tests on real Q800 hardware show that the ESCC is addressable at multiple locations
within the ESCC memory region - at least 0xc000, 0xc020 (as expected by the MacOS
toolbox ROM) and 0xc040.

All released NetBSD kernels before 10 use the 0xc000 address which causes a fatal
error when running the MacOS booter. Add a single memory region alias at 0xc000
to enable NetBSD kernels to start booting under QEMU.

This determines whether the Apple Sound Chip (ASC) is set to enhanced mode

a lot of older software only works with the older ASC chip.

Adding this as a machine parameter allows QEMU to be used as an developer aid

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.
