[PATCH 6/8] samples: move pcmcia example code from Documentation

[Shuah Khan]

Move pcmcia examples to samples and remove it from Documentation
Makefile. Create a new Makefile to build pcmcia. It can be built
from top level directory or from pcmcia directory:

Run make -C samples/pcmcia or cd samples/pcmcia; make
