x86: Don't spam POST80 codes with slow IO functions
This patch prevents u-boot from "spamming" random progress codes on a port 80 "post card". The previous version of this patch just removed the delays in the "slow" IO functions, as they do not need to be slow, however, this patch is less intrusive. It uses another unused port that is often used by BIOSes (and the Linux Kernel) for small delay timing purposes.
