Added missing txtmode config for T420
Rolled back the recent SeaBIOS revision update, which
therefore removes these SeaBIOS patches:
* 9029a010 kconfig: fix the check-lxdialog.sh to work with gcc 14+
* 8863cbbd ahci: add controller reset
* df9dd418 update pci_pad_mem64 handling
* a4fc1845 add romfile_loadbool()
* a2725e28 drop acpi tables and hex includes
* 35aa9a72 drop obsolete acpi table code
* 1b598a1d usb-hid: Support multiple USB HID devices by storing them in a linked list
Technically, I need only revert instead to revision df9dd418, but
that and the other revisions above contain changes that may possibly
cause other breakage.
We know the old revision worked, so roll back these 7 SeaBIOS commits.
Now I will re-compile the 25.04 release and re-upload it as rev1.
