[PATCH 3/4] drm/i915: Add intel_gpu_freq() and intel_freq_opcode()

[ville.syrjala@xxxxxxxxxxxxxxx]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Rename the vlv_gpu_freq() and vlv_freq_opecode() functions to have
an intel_ prefix, and handle non-VLV/CHV platforms in them as well.
Leave the vlv_ names around for now since they're currently used.
