Subject: [PATCH 4/7] clocksource: prima2: fix ftrace

Currently prima2 timer can be used as a scheduler clock, we properly
marked sirfsoc_read_sched_clock() as notrace. But we then call another
function sirfsoc_timer_read() that _wasn't_ notrace.

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