Revert "ARM: 7830/1: delay: don't bother reporting bogomips in /proc/cpuinfo"
Commit 9fc2105aeaaf ("ARM: 7830/1: delay: don't bother reporting
bogomips in /proc/cpuinfo") breaks audio in python, and probably
elsewhere, with message
FATAL: cannot locate cpu MHz in /proc/cpuinfo
I'm not the first one to hit it, see for example
https://theredblacktree.wordpress.com/2014/08/10/fatal-cannot-locate-cpu-mhz-in-proccpuinfo/
https://devtalk.nvidia.com/default/topic/765800/workaround-for-fatal-cannot-locate-cpu-mhz-in-proc-cpuinf/?offset=1
Reading original changelog, I have to say "Stop breaking working setups.
You know who you are!".
