[RFC PATCH 2/2] init: calibrate: don't print out bogomips value on boot

BogoMIPs is a confusing concept, 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, bogus (geddit?) value.
