[PATCH] hardcoded bdf numbers in sb700_early_init.c get serial output on ASUS M4A77TD-PRO

[xdrudis]

Hello. I rewrote my earlier patch to romcc_io.h (where I banned some
device ranges from pci_locate_device) because it was too
aggressive. With this patch to sb700_early_setup.c I achieve the same
on my board (serial output, and it hangs in the same place), but
hopefully with less breakage for other boards. I first tried to hardcode
PCI bus, device and function in sb700_lpc_init() only but it did hang
elsewhere, so I finally thought it more coherent to hardcode all
devices in the file than just some functions, and it works for me. I
still have the doubt of why was there a pci_locate_device in the first
place, since from my more than limited knowledge it does not look like
the devices in sb700 may appear in other bus,device,function
addresses. But the original even had an error message at one place for
when the device was not found.

Please review and/or test and commit if you think appropiate (I guess 
it's not urgent, since my board still does not boot).

This patch applies to svn 5739

Thank you for commiting my previous patches.

Now I plan to have a look at fidvid.c and AMD's Bios and Kernel
Developer Guide. I'm not sure I'll be able to fix much, and it may
take me a while. I guess it's better not to send patches or anything
until I get something that works for me.
