ftrace: split out hardirq ftrace code into own header
Impact: moving of function prototypes into own header file
ftrace.h is too big of a file for hardirq.h, and some archs will fail
to build because of the include dependencies not being met.
This patch pulls out the required prototypes for hardirq.h into a smaller
and safer ftrace_irq.h file.
