[PATCH 3/7] clocksource: pistachio: fix ftrace

[Jisheng Zhang]

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.
