x86: Reduce verbosity of "TSC is reliable" message
On modern systems, the kernel prints the message
Skipping synchronization checks as TSC is reliable.
once for every non-boot CPU.
This gets kind of ridiculous on huge systems; for example, on a
64-thread system I was lucky enough to get:
$ dmesg | grep 'TSC is reliable' | wc
63 567 4221
There's no point to doing this for every CPU, since the code is
just checking the boot CPU anyway, so change this to a
printk_once() to make the message appears only once.
