efi: vars: Remove deprecated 'efivars' sysfs interface
Commit 5d9db883761a ("efi: Add support for a UEFI variable filesystem") dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to replace the efivars sysfs interface that was used up to that point to expose EFI variables to user space. The main problem with the sysfs interface was that it only supported up to 1024 bytes of payload per file, whereas the underlying variables themselves are only bounded by a platform specific per-variable and global limit that is typically much higher than 1024 bytes. The deprecated sysfs interface is only enabled on x86 and Itanium, other EFI enabled architectures only support the efivarfs pseudo-filesystem. So let's finally rip off the band aid, and drop the old interface entirely. This will make it easier to refactor and clean up the underlying infrastructure that is shared between efivars, efivarfs and efi-pstore, and is long overdue for a makeover.
