x86/mm: Don't print out SRAT table information 



This per CPU log is becoming longer with more and more CPUs in system,
which slows down the boot process due to the serializing nature of
printk().

The value of this information is dubious and it can be retrieved by lscpu
from user space if required..

Downgrade the printk() to pr_debug() so it is still accessible for debug
purposes.
