[v4,3/4] nfit: move to nfit/ sub-directory

Commit Message

Dan Williams July 24, 2016, 5:26 a.m. UTC

With the arrival of x86-machine-check support the nfit driver will add a
(conditionally-compiled) source file.  Prepare for this by moving all
nfit source to drivers/acpi/nfit/.  This is pure code movement, no
functional changes.
