drm/i915: fix i9xx_crtc_clock_get for multiplied pixels
The dpll actually runs at the port clock so we don't need
to multiply it again with the pixel multiplier to get the
adjusted_mode.clock. This is in contrast to the ironlake
pixel clock readout code which uses the fdi dotclock: That
one does _not_ run with multiplied pixels.
This issue goes back to the original clock readout code added
in
