[PATCH 1/1] time/sched_clock: move sched_clock_register() out of .init section

[Maxim Kochetkov]

The sched_clock_register() is widely used by clocksource timer
drivers. The __init prefix forces them to be initialized using
macro TIMER_OF_DECLARE with __init prefixed function.

Clocksource devices can be consumers of some external irq, clocks,
resets, e.t.c. Such devices can't be correctly probed if this
dependencies are provided by platform drivers. Because of regular
platform devices are not probed at this moment.

We can convert clocksource drivers to platform device drivers to
fix this issue, but __init prefix in sched_clock_register()
prevents it.

So lets drop __init prefix to allow platform device drivers to use
sched_clock_register().
