This is the only spot in the whole kgdb series where kgdbcons is used
outside its home kernel/kgdb.c. Is this really required in order to use
the kgdb console with PXA? And why is it like this only for this platform?

[Note that this forces kgdbcons to become non-static, ie. we will have
to fully initialize it, unlike it is done so far...]

Thanks,
Jan
