drm/i915: clean up and simplify i9xx_crtc_mode_set wrt PLL handling

Browse source

Flat out skip anything to do with PLL if we have a DSI encoder (and thus
DSI PLL). Also skip PLL computation if the encoder has already set
clocks. This allows for some tidying up of the code, including a
superfluous call to intel_limit() for LVDS downclock path.
