cpufreq/amd-pstate-ut: Add fix for min freq unit test

commit 642aff3964b0f ("cpufreq/amd-pstate: Set the initial min_freq to
lowest_nonlinear_freq") changed the initial minimum frequency to lowest
nonlinear frequency, but the unit tests weren't updated and now fail.

Update them to match this same change.
