[PATCH 2/7] clocksource: samsung_pwm_timer: fix ftrace

Currently samsung_pwm_timer can be used as a scheduler clock, we properly
marked samsung_read_sched_clock() as notrace. But we then call another
function samsung_clocksource_read() that _wasn't_ notrace.

This patch fix this by adding notrace attribute to the
samsung_clocksource_read() function.
