[PATCHES] Convert various pc98 drivers from timeout() to callout()

I have three patches to convert various pc98 drivers from timeout() to 
callout().  For the fdc driver I took a more drastic approach and have 
attempted to port the PC98 support into the main fdc driver:

The pckbd driver needs a similar change to what I recently comitted to atkbd:

For the olpt driver, I just did a simple conversion:

These patches are against HEAD but likely apply to 9 and 10 as well.
