Henrique de Moraes Holschuh 275014ae46 thinkpad-acpi: fix detection of old ThinkPads 
There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.

This breaks module loading on, e.g.  a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.

Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.

This fixes a serious regression, introduced by commit
e675abafcc, "thinkpad-acpi: be more strict
when detecting a ThinkPad".
