Adding a SPI driver for pn532

Browse source 
The driver seems to work well.
I tested it on Linux with i.mx233-based board using hardware SPI.
I tried to modify the build files as well, but it's probably a little messy.
I'm not sure whether it will work on other *nix OSes,
so it's probably better to limit the driver to Linux only using build system.
