Mainly, the "public APIs" added in this commit probably need to be separated into
their own compilation unit, because they need to be compiled into SMM.

Currently, everything's implemented and exported in the same file, and that
means we're compiling the PC80 keyboard init code into SMM as well. I don't think
it functionally changes anything (assuming nobody calls keyboard init in SMM...),
but it's definitely not correct.

As for the status of this patchset, I recently relocated long distance and won't be
able to work on anything coreboot-related until at least the start of next year.
If there's interest in merging sooner, I have no problem if someone takes over the
patchset.
