crosperf: Setup intel_pstate
Setup intel_pstate in kernel command line to a value from global
settings "intel_pstate" argument (default '').
Added crosperf "--no_hwp" argument for a shortcut change.
Kernel command line will be updated only if hwp is supported by CPU.
Intel_pstate HWP feature can be disabled via kernel command line argument
intel_pstate=no_hwp. See
https://www.kernel.org/doc/html/v4.12/admin-guide/pm/
intel_pstate.html#kernel-command-line-options-for-intel-pstate
BUG=chromium:966514
TEST=tested on eve, rammus (supported), kefka, samus (not supported),
scarlet (arm).
