Merge tag 'efi-efivars-removal-for-v5.20' of git://git./linux/kernel/git/efi/efi

Pull efivars sysfs interface removal from Ard Biesheuvel:
 "Remove the obsolete 'efivars' sysfs based interface to the EFI
  variable store, now that all users have moved to the efivarfs pseudo
  file system, which was created ~10 years ago to address some
  fundamental shortcomings in the sysfs based driver.

  Move the 'business logic' related to which EFI variables are important
  and may affect the boot flow from the efivars support layer into the
  efivarfs pseudo file system, so it is no longer exposed to other parts
  of the kernel"
