rockchip: add support for rk3288
The rk3288 is a 4-core Cortex-A12 SoC and shares a lot of features
with later SoCs.
Working features are general non-secure mode (the gic needs special
love for that), psci-based smp bringing cpu cores online and also
taking them offline again, psci-based suspend (the simpler variant
also included in the linux kernel, deeper suspend following later)
and I was also already able to test HYP-mode and was able to boot
a virtual kernel using kvm.
