Andrew Turner 4e46a66e4a Add support for the Raspberry Pi 2. As the chip is based on the bcm2835 in
the Raspberry Pi B we support most of the devices are already supported,
however the base address has changed.

A few items are not working, or missing. The main ones are:
 * DMA doesn't work in the sdhci driver.
 * Enabling vchiq halts the boot, may be interrupt related.
 * There is no U-Boot port yet so the DTB is embedded in the kernel.

The last point will make it difficult to boot FreeBSD, however there is
support for the Raspberry Pi 2 in the U-Boot git repo. As I have not tested
this it is left as an open task to create a port to build.
