nfit: move to nfit/ sub-directory
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. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
