q800: implement mac rom reset function for BIOS-less mode
On Linux, calling `reboot(RB_AUTOBOOT);` will result in
arch/m68k/mac/misc.c's mac_reset function being called. That in turn
looks at the rombase (or uses 0x40800000 is there's no rombase), adds
0xa, and jumps to that address. At the moment, there's nothing there, so
the kernel just crashes when trying to reboot. So, this commit adds a
very simple implementation at that location, which just writes to via2
to power down. We also correct the value of ROMBASE while we're at it.
