4dd5845f49 bmips: fix SMP CPU mapping 
SMP isn't supported on BCM6358 since it has a shared TLB. Some boards boot
with CPU #1 instead of CPU #0, and this is currently not supported do to a
smp-bmips bug.

029093a302 bmips: add new target 
This target has full device tree support, thus reducing the number of
patches needed for bcm63xx, in which there's a patch for every board.

The intention is to start with a minimal amount of downstream patches and
start upstreaming all of them.

Current status:
 - Enabling EHCI/OHCI on BCM6358 causes a kernel panic.
 - BCM63268 lacks Timer Clocks/Reset support.
 - No PCI/PCIe drivers.
 - No ethernet drivers.
