q800: add ESCC alias at 0xc000
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.
