5b625181fb Documentation: Mark the 'efivars' sysfs interface as removed
The 'efivars' sysfs interface was removed in commit 0f5b2c69a4 ("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.

2dcc51b3fe docs: filesystems: add info about efivars content
When an EFI variable is reading from:

/sys/firmware/efi/efivars

(for example using "hexdump"), the first 4 bytes of the
output are not the real EFI variable data, but the variable
attributes (in little-endian format).
