[LinuxBIOS] [PATCH] Add early serial support for Fintek F81705f

[Corey Osgood]

My email address is different in the headers, because I'll be losing my
Verizon email address soon, due to the Fairpoint takeover. Not sure if
the sign-off should be this email or that one, but they're both mine.

This is the first patch for the Fintek F81705f for early serial support,
a second one will follow once I'm able to test the post-RAM port. I've
tested this on the Jetway J7F2WE1G, and it seems to work fine.
