Subject[PATCH] Add support for EDD4 fields and types.
Date
Back in 2010, t13 EDD version 4 added a couple of storage types, some
host bridge types (that are pretty much all represented identically),
and a couple of fields on existing storage types.

This change makes the driver expose those to userland.
