sata_mv: shorten register names

Rename a slew of register name constants in sata_mv,
removing the _OFS suffix from them, and shortening some
of them in other ways as well.

Also, bump up the version number to reflect all recent changes.

In theory, no actual changes to the generated code,
other than the version number bump.
