    drm/i915: Relax RPS contraints to allows setting minfreq on idle

    When we idle, we set the GPU frequency to the hardware minimum (not user
    minimum). We introduce a new variable to distinguish between the
    different roles, and to allow easy tuning of the idle frequency without
    impacting over aspects of RPS. Setting the minimum frequency should be a
    safety blanket as the pcu on the GPU should be power gating itself
    anyway. However, in order for us to do set the absolute minimum
    frequency, we need to relax a few of our assertions that we do not
    exceed the user limits.
