tools: move pcmcia crc32hash tool from Documentation
Move pcmcia crc32hash tool from Documentation to tools/pcmcia and remove it from Documentation Makefile. Update location information for this tool. Create a new Makefile to build pcmcia. It can be built from top level directory or from pcmcia directory: Run make -C tools/pcmcia or cd tools/pcmcia; make Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

The hex value after "pa" is the hash of product ID string 1, after "pb" for
string 2 and so on.
-Alternatively, you can use crc32hash (see Documentation/pcmcia/crc32hash.c)
+Alternatively, you can use crc32hash (see tools/pcmcia/crc32hash.c)
to determine the crc32 hash. Simply pass the string you want to evaluate
as argument to this program, e.g.:
-$ ./crc32hash "Dual Speed"
+$ tools/pcmcia/crc32hash "Dual Speed"
