[PATCH] Bring Moxa serial back into being

[PATCH] Bring Moxa serial back into being

Moxa have released several driver updates now including support up to
2.6.8 but don't themselves feel its worth the effort of doing a cleaned
up merge for the base kernel.  So I pulled their latest driver release
(1.8) and removed all the macro gunge that makes it build on
2.2.0->2.6.8.  I then fixed it to run on 2.6.9/10 and fixed a bug in the
break handling.

It still doesn't do PCI hotplug but I don't have any PCI moxa cards to
really tackle that particular case.

I've also merged Adriank Bunk's two 'could be static' changes into this
diff set.
