autotest: stop relying on cpufreq in autotests for newer platforms that don't have it

Project Member Reported by kirtika@google.com, Feb 23 2018 
My understanding is that cpufreq has been phased out in favor of intel_pstate or similar in newer platforms (eve, <redacted>). 
Some of our autotest plumbing uses it implicitly or explicitly.
e.g. audio_Microphone test fails on my <redacted> P1 board with this stack-trace. Is cpufreq ever going to be present on this platform?

+ Rajat for experience on Poppy.

Ok, I dug some more on my Eve, and this bug is a mistake - cpufreq is present on Eve (as a state-keeping entity?) and intel_pstate is the "scaling_driver" (one of the available ones) that it uses. 

Only question then is why does my <redacted> board not have cpufreq entries populated? 
Leaving this open in case Todd/Duncan have thoughts on needed cpufreq changes.

Comment 2 by tbroch@chromium.org, Feb 23 2018 

my guess is kernel is being built w/o CONFIG_CPU_FREQ ... at least that appears to be where the sysfs path originates.

drivers/cpufreq/cpufreq.c:
show_one(cpuinfo_max_freq, cpuinfo.max_freq);

Please take a look at this ASAP.  The failures reported in  Issue 822007  are (along with other issues) keeping the pfq red.

RE: Comment 4-
After 3 days of solid red, amd64-generic-chromium-pfq turned green again with build #11759, and has been green since:
  https://uberchromegw.corp.google.com/i/chromeos/builders/amd64-generic-chromium-pfq?numbuilds=200
I guess this is no longer urgent...?
