tools: PCI: Change pcitest compiling process 



Change tool compiling process in order to be build using the same
mechanism used in other linux tools (e.g. iio, perf, etc). This will
allow in future the buildroot tool to build and integrate this tool in
a more expeditious way.

Update documentation accordingly.

pcitest.sh added in tools/pci/ can be used to run all the default PCI endpoint

tests. Before pcitest.sh can be used pcitest.c should be compiled using the

tests. To compile this tool the following commands should be used:

following commands.





	cd <kernel-dir>

	# cd <kernel-dir>

	make headers_install ARCH=arm

	# make -C tools/pci

	arm-linux-gnueabihf-gcc -Iusr/include tools/pci/pcitest.c -o pcitest



	cp pcitest  <rootfs>/usr/sbin/

or if you desire to compile and install in your system:

	cp tools/pci/pcitest.sh <rootfs>



	# cd <kernel-dir>

	# make -C tools/pci install



The tool and script will be located in <rootfs>/usr/bin/
