Refactor Statistical Profiling Extensions implementation
Factor out SPE operations in a separate file. Use the publish
subscribe framework to drain the SPE buffers before entering secure
world. Additionally, enable SPE before entering normal world.
A side effect of this change is that the profiling buffers are now
only drained when a transition from normal world to secure world
happens. Previously they were drained also on return from secure
world, which is unnecessary as SPE is not supported in S-EL1.
