pp5020: use ipod firmware timings for ATA PIO.

Some mSATA adapters seem to have trouble working with Rockbox using our
normal PIO timings; the timing value we use is probably out of spec and
is different to the OF. Switch to using the OF's timings according to
which PIO mode we select. This may not completely resolve problems with
these adapters but allows Rockbox to boot and play audio.
