The 'efivars' sysfs interface was removed in commit 0f5b2c69a4cb ("efi: vars: Remove deprecated 'efivars' sysfs interface"), but the ABI documentation was not updated properly. Strip down the documentation file for /sys/firmware/efi/vars to a very basic description of what the interface was about, add a section about the rough removal timeline, and inform the reader about the intended replacement.
