clocksource: Use pr_info() for "Checking clocksource synchronization" message
[ Upstream commit 1f566840a82982141f94086061927a90e79440e5 ]
The "Checking clocksource synchronization" message is normally printed
when clocksource_verify_percpu() is called for a given clocksource if
both the CLOCK_SOURCE_UNSTABLE and CLOCK_SOURCE_VERIFY_PERCPU flags
are set.
It is an informational message and so pr_info() is the correct choice.
