sam: more work on the ATA disk interface

We can now detect Atom and Atom Lite, as well as select the right 8 or 16bit
handling for them. The 16bit handlers are hairy because we can be doing an
I/O that crosses a page boundary. This needs a bit of thought to keep it
efficient. Atom Lite on the other hand appears to be trivial.
