Rename ARM_INTRNG and MIPS_INTRNG to INTRNG. This will help with machine
independent code that needs to know about INTRNG such as PCI drivers.

Implement bcm2836 interrupt controller for INTRNG and enable it
on RPI2 by default.

Make interrupt dispatching MP safe. Use GPU interrupt bit in per-core
interrupt status register to process shared interrupts only if the bit
is active and only on core to which they are routed.

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.
