nfit: move to nfit/ sub-directory

djbw · djbw · commit bdf97013ced5 · 2016-07-24T08:04:04.000-07:00
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.
