arm: Add support for the Broadcom Northstar SoCs
The original Northstar is an ARM SoC series that comprise
BCM4709x and BCM5301x and uses a dual-core Cortex A9, the
global timer and a few other things.
This series should not be confused with North Star Plus
(NSP) which is partly supported by U-Boot already.
The SoC is well supported by the Linux kernel and OpenWrt
as it is used in many routers.
Since we currently don't need any chip-specific quirks
and can get the system up from just the device tree, a
mach-* directory doesn't even need to be added, just
some small Kconfig fragments.
