BogoMIPs is a confusing concept to the ill-informed, so allow
architectures to print it only if they find it worthwhile. The delay
calibration code should stick to lpj and avoid trying to draw any
correlation with BogoMIPs, which may be a fixed value derived from a
timer frequency independent of the CPU clock speed.

This is mostly cosmetic, but we've killed bogomips from the cpuinfo
on ARM and arm64, so this would be the final nail on the coffin...
