ftrace: fix boot trace sched startup
Impact: boot tracer startup modified
The boot tracer calls into some of the schedule tracing private functions
that should not be exported. This patch cleans it up, and makes
way for further changes in the ftrace infrastructure.
This patch adds a api to assign a tracer array to the schedule
context switch tracer.
