clocksource: Use pr_info() for "Checking clocksource synchronization" message 

stable inclusion
from stable-v6.6.79
commit 0cc5bb930079b35cc5f569367420973c337d4bae
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC76

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0cc5bb930079b35cc5f569367420973c337d4bae



--------------------------------

[ 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.
