[PATCH] bsps/raspberrypi: Add FDT defines to build options

[Alan Cudmore]

Hi,
This patch works for me. I can build and run the latest rtems master
branch samples on the RPI 2 and 3.
The samples do not run on the single core models, but it is not
related to this patch. I have a patch for the single core models, and
when combined with this patch I can get the samples to run on RPI
Zero, Zero W, Pi A+, Original Pi Model B+, Pi 2, and Pi 3.

Thanks,
Alan
