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
