f54b91fdfa ARM: rockchip: Add cpu hotplug support for RK3XXX SoCs
Adds ability to shutdown all CPUs except the first one
(since it might be special for a lot of platforms).
It is now possible to use kexec which requires such a feature.

26ab69cb4c ARM: rockchip: convert smp bringup to CPU_METHOD_OF_DECLARE
With the newly introduced CPU_METHOD_OF_DECLARE is not necessary anymore
to reference the relevant smp_ops in the board file, but instead it can
simply be set by the enable-method property of the cpu nodes.

a7a2b3118b ARM: rockchip: add smp bringup code
This adds the necessary smp-operations and startup code to use
additional cores on Rockchip SoCs.

We currently hog the power management unit in the smp code, as it is
necessary to control the power to the cpu core and nothing else is
currently using it, so a generic implementation can be done later.
