nwztools: add a new plattools directory with code to run on the device

This is code is intended to development into a library of code for the NWZ that
will be useful to write the "bootloader" on those device. At the same time, it
comes with test programs that are easy to run in firmware upgrade mode and also
provide a great test bench for the library. At the moment, two test programs are
available:
- test_display: simply prints two messages using /usr/bin/lcdmsg
- test_keys: displays input key event
