drm/i915: Grab the pixel clock from adjusted_mode not requested_mode

Browse Source 
i9xx_set_pipeconf() attempts to get the current pixel clock from
requested_mode. requested_mode.clock may be totally bogus, so the
clock should come from adjusted_mode.

v2: Dropped the intel_compute_config() hunk due to killing of the
    INTEL_FDI_FREQ check
