Raspberry PI 2 support added

Recent commits just added support for the Raspberry Pi 2 inside NetBSD.

It comes with all the peripherals and GPU acceleration features that are available on the first Raspberry Pi, together with a Cortex A7 processor capable of running at 900MHz.

Head directly to the installation notes available in Raspberry Pi's entry in the NetBSD Wiki for a quick way to get your system up and rolling.

Stay tuned for multiprocessor support!
