chore(spe): rename spe_disable() to spe_stop()

During CPU power down, we stop the profiling by calling spe_disable()
function. From TF-A point of view, enable/disable means the avaibility
of the feature for lower EL. In this case we are not actully disabling
the feautre but stoping it before power down.
