The tuneproc() method in both these drivers failed to set the drive's own speed.
Fix this by renaming the function and "wrapping around it" the new tuneproc()
method. Switch back to calling tuneproc() in the PIO fallback code.
While at it, also convert the rest of the PIO timing code into proper C. :-)
