[igt-dev] [PATCH i-g-t] tests/i915_pm_freq_api: Set min/max to expected values

[Vinay Belgaumkar <vinay.belgaumkar@intel.com>]

A prior(rps) test leaves the system in a bad state causing failures
in the basic test. Set min/max to expected values before running it.
Test will restore values at the end.
