Currently when we're validating cpu on boot stage we assume that cpu level
won't ever be greater than two digits. In particular the check_cpu() helper
ensures to be so. Still the cpu_name() helper is a way too far from
check_cpu() routine internals so I think better to be on a safe side
and prevent any possible overrun errors when printing cpu name.
For this sake just increase the buffer up to be able to keep any level.
