From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

Due to the multiple watchdogs available on the mcom
device efibootguard select the iTCO watchdog and the
Linux kernel selects the WDAT watchdog which leads to
an system reboot during booting as the Linux kernel no
longer drives the iTCO watchdog.
