For openbmc, all the hardware access is required to go via sbefifo.
Currently some of the operations are hacked in to go via sbefifo.
This patchset removes temporary hacks and adds infrastructure to create
sbefifo backend.

Also fix couple of bugs in libsbefifo.

V2 changes:
  - Rebased on top of latest master
    (resolved conflicts and add missing code due to upstream changes)
