Currently pistachio can be used as a scheduler clock, we properly marked pistachio_read_sched_clock() as notrace. But we then call another function pistachio_clocksource_read_cycles() that _wasn't_ notrace.
This patch fix this by adding notrace attribute to the pistachio_clocksource_read_cycles() function.
