x86: Don't print number of MCE banks for every CPU
The MCE initialization code explicitly says it doesn't handle asymmetric configurations where different CPUs support different numbers of MCE banks, and it prints a big warning in that case. Therefore, printing the "mce: CPU supports <x> MCE banks" message into the kernel log for every CPU is pure redundancy that clutters the log significantly for systems with lots of CPUs.
