drm/i915: Use port clock to set correct N value 

Use port_clock to check the clock values in n/cts lookup table instead
of crtc_clock. As port_clock is already adjusted based on color mode set
(8 bit or deep color), this will help in checking clock values for deep
color modes from n/cts lookup table.
