update Toshiba ohci quirk DMI table

I upgraded my Toshiba Satellite BIOS recently to see if it would fix an ACPI related problem I have
(http://bugzilla.kernel.org/show_bug.cgi?id=5727). Unfortunately, it didn't, and moreover, Toshiba chose to change the system version in the DMI table with the update, causing the OHCI1394 related quirk to break. This patch updates the DMI table for the quirk to include Toshiba's new version name for this machine; I've tested it and it seems to work fine.
