Move ARM_L2_PIPT option to std.armv6 for all armv6 platforms.
Only L2 PIPT cache is supported for __ARM_ARCH >= 6.

In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.

Add the SMP support for Raspberry Pi 2 (BCM2836).

Tested with the build of some ports and a buildworld.

Set ARM_L2_PIPT for A10 and RPI2, they are probably missing by accident.

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.
