Introduce framework for CPU specific operations
This patch introduces a framework which will allow CPUs to perform
implementation defined actions after a CPU reset, during a CPU or cluster power
down, and when a crash occurs. CPU specific reset handlers have been implemented
in this patch. Other handlers will be implemented in subsequent patches.
Also moved cpu_helpers.S to the new directory lib/cpus/aarch64/.
