cpufreq/amd-pstate: Loosen requirement on lowest nonlinear frequency != min freq

This requirement was introduced by commit 8f8b42c1fcc93 ("cpufreq:
amd-pstate: optimize the initial frequency values verification")
specifically to aid in debugging BIOS issues with invalid _CPC tables
on some older systems.

This requirement is too tight for new systems though as some systems
actually have lowest nonlinear frequency identical to minimum
frequency.  Allow that combo to work.
