A mistake was made that only AMDI0007 was set to rev of "2", but
it should have been also set for AMDI008. If an ID is missing from
the _HID table, then assume it matches Rembrandt behavior.

This implicitly means that if any other behavior changes happen
in the future missing IDs must be added to that table.
