Since this is a new, non-PATA, non-SATA controller/device setup, there 
are a few general questions,

- what to do about cable detection?  unless it matters, we could simply 
assume a fixed cable type, since its a virtual link.

- what is the proper reset method?  to kick a device (and controller) 
into action, we will COMRESET via the SATA phy, or at the very least SRST.

- is set-xfer-mode properly emulated?  normally we look at the ATA 
device's IDENTIFY DEVICE page, and choose a transfer xfer from that info.
