drm/i915: Set softmin frequency on idle->busy transition

If the GPU load is low enough, it's possible that we'll be stuck at idle
frequency rather than transition into softmin frequency requested by
userspace.

v2: Use intel_set_rps, drop vlv_set_idle
v3: Back to vlv_set_idle, clamp to valid range
v4: Place intel_set_rps at the end
