"mem=nopentium" would clear the PSE bit in boot_cpu_data, but the CPU
detection later would overwrite it again from CPUID.

The large pages would be correctly disabled, but cpu_has_pse was lying.

This patch makes sure it stays clear when the option is given.

I also took the liberty to remove these obnoxious cpu capability
printks who give no use information (the data can be either gotten
from CPUID in user space in raw form or from /proc/cpuinfo processed)
