From: "Gabriel L. Somlo" <somlo@cmu.edu>

Table definitions for types 4 and 17 are only up to v2.0,
so add fields specified in smbios v2.3, as expected (and
advertised) by the SeaBIOS smbios entry point structure.

In particular, OS X guests insist on type 17 being v2.3
compliant, to avoid GUI crashes when "about this mac" is
chosen in the Finder menu.
