m68k: Add NeXTcube machine
It is still quite incomplete (no SCSI, no floppy emulation, no network,
etc.), but the firmware already shows up the debug monitor prompt in the
framebuffer display, so at least the very basics are already working.
This code has been taken from Bryce Lanham's GSoC 2011 NeXT branch at
https://github.com/blanham/qemu-NeXT/blob/next-cube/hw/next-cube.c
and altered quite a bit to fit the latest interface and coding conventions
of the current QEMU.
