util/e6400-flash-unlock: Update to upstream version
This updates lbmk's copy of e6400-flash-unlock to commit c5567fece479
(README.md: Update with info about broader device support) in my
upstream repo.

Changes:
- Theoretical support for any Dell system that implements that flash
  descriptor override command. This is done by reading base address
  registers at runtime instead of hard coding them for specific devices.
  Tested on the Latitude E6400 and Latitude E6430.
- Support for OpenBSD. It compiles, runs, and behaves as expected,
  though I have not actually tested internally flashing with flashrom
  yet. It should work though, as the program checks if the descriptor
  override is set and the BIOS Write Enable is able to be set to 1, which
  is all that is needed to internal flash.
- Integrated changes made in the lbmk copy
- Moved operating system accessor implementations to their own file

It should be fully functional, though minor formatting and cleanup
changes are still planned.

Nicholas Chin eb32e49327 util/e6400-flash-unlock: restore README
when nicholas added this, he removed the README because it's
going on libreboot.org instead. however, i merged a WIP version
of his page for now because i want to get the e6400 going in
libreboot sooner. so, temp-readding this README. will just
link to this on codeberg or something, from the lb docs

NOTE: I didn't write this README, hence author field set
in the commit. Nicholas wrote it, but I (Leah Rowe) am just
adding it. so, git author set to nicholas, not me

Add E6400 flash unlock utility
Adding it to lbmk for now as it is not yet in coreboot. If it is merged
into coreboot we can just reference the one there. The original README
will be incorporated into a new page on lbwww, so README.md just points
to a placeholder URL that should match the new page.
