Add some more elements to struct ataparams. 

These mostly concern the new Long Physical Sectors
and Long Logical Sectors feature sets.

Information from a draft of ACS-2, with some additional
in-between members and bits being borrowed from OpenBSD.

There's lots more in ACS-2 we could add, but for the most
part it would be superfluous.

XXX: Some elements marked as reserved no longer are,
and some elements we still reference are now obsolete.
