[PATCH v2 3/3] tools: move pcmcia crc32hash tool from Documentation

[Shuah Khan]

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

 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 tools/pcmcia/crc32hash.c)

 as argument to this program, e.g.:
