Subject: [PATCH] clocksource/drivers/ingenic: Fix section mismatch

The function ingenic_tcu_get_clock() is annotated for the __init
section but it is actually called from the online cpu callback.

That will lead to a crash if a CPU is hotplugged after boot time.

Remove the __init annotatation for the ingenic_tcu_get_clock()
function.

Fixes: f19d838d08fc (clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT)
