de2f1dfebd Turn up Nexus10 CPU frequencies
The previous list was created from scaling_min_freq and scaling_max_freq
instead of cpuinfo_min_freq and cpuinfo_max_freq which are the actual mins
and maxes, not the current (transient) settings of the governor.

Before:
Test-Release: 61 minutes
Perf-Debug: 41 minutes

After:
Test-Release: 32 minutes
Perf-Debug: 16 minutes

1c8092ac64 Make cpu scaling more robust
Some bots, especially the Nexus 7s, seemed to occasionally
fail when setting the CPU frequency.  I was unable to
repro this behavior, so this is a shotgun approach.

We add a 5 second delay between setting and checking,
checking frequency using scaling_cur_freq instead of
scaling_setspeed, set the min_freq as well as max_freq,
and retry up to 3 times if setting cpu frequency fails.
