clocksource/drivers/ti-32k: Prevent ftrace recursion
Currently ti-32k can be used as a scheduler clock. We properly marked
omap_32k_read_sched_clock() as notrace but we then call another
function ti_32k_read_cycles() that _wasn't_ notrace.
Having a traceable function in the sched_clock() path leads to a
recursion within ftrace and a kernel crash.
Fix this by adding notrace attribute to the ti_32k_read_cycles()
function.
