The chip really is weird.  For some reason, I can't do ATA PIO from mmio
TF but can do so using BAR{0,2}.  It does have sff-compliant BAR0-3 but
no BMDMA at BAR4.  And it can't do more than 256 sects at a time.  Ah...
also, SRST nor phy reset via SControl doesn't give valid device
signature.  Only hardreset via IDMA_CTRL works.  Bah...

Anyways, I'm getting there.  My 1622 is happily transferring 76M file
without problem in and out of a seagate harddrive using pio mode.  So,
please standby.
