[PATCH 1/5] clocksource/drivers/arm_arch_timer: Rename arch_timer_probed to reflect behaviour

From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

The arch_timer_probed function returns whether the given time doesn't
need to be probed. This can be the case when the timer has been probed
already, but also when it has no corresponding enabled node in DT.

Rename the function to arch_timer_needs_probe and invert its return value
to better reflect the function's purpose and behaviour.
