Boards: Formalize intel piix4 gpo setting

The function intel_piix4_gpo_set includes proper gpo pin checking, and
gpo pin enables when necessary.

This is a leftover from soyo SY-6BA+III code that turned out to be
unnecessary, but still used for the epox ep-bx3 board enable which it
cleans up and clarifies.

Difference to old code:
* typical bios delay io port 0xEB now never gets touched.
* pci config byte 0xB0 was not altered before.

Corresponding to flashrom svn r803.
