drm/i915: Relax RPS contraints to allows setting minfreq on idle
it is now possible that the current frequency will drop be the user
specified minimum frequency to the "idle" or RPn frequency. Update the
pm_rps tests to reflect that droping below the user specified minimum
is no longer considered a failure.
v2: Add check RPn <= current freq. (Me)
