sun7i: Add support for taking CPUs offline via PSCI Based on the original version by Marc Zyngier. It adds a psci_cpu_off implementation for the A20 SoC. The mechanism works by first preparing the calling CPU to go offline (disable and flush cache, disable SMP), then requesting CPU 0 to pull the plug. The request is sent as FIQ on SGI15.
