Julien Thierry 5d6168fc61 clocksource/drivers/arm_arch_timer: Don't trace count reader functions 
With v5.2-rc1, The ftrace functions_graph tracer locks up whenever it is
enabled on arm64.

Since commit 0ea415390c ("clocksource/arm_arch_timer: Use
arch_timer_read_counter to access stable counters") a function pointer
is consistently used to read the counter instead of potentially
referencing an inlinable function.

The graph tracers relies on accessing the timer counters to compute the
time spent in functions which causes the lockup when attempting to trace
these code paths.

Annotate the arm arch timer counter accessors as notrace.

Fixes: 0ea415390c ("clocksource/arm_arch_timer: Use
       arch_timer_read_counter to access stable counters")
