Suraj Kandpal 5abc20e39d drm/i915/ddi: add helper to compute DDI clock frequency
Add intel_ddi_link_symbol_clock() to return the DDI clock frequency for
a given port clock:
  DP 8b/10b : rate
  DP 128b/132b (UHBR) : (10 / 32) * rate
  HDMI FRL  : (10 / 18) * rate
  HDMI TMDS : rate

The DP case reuses intel_dp_link_symbol_clock().
This will help in upcoming commits to decide value to be written
in DDI_CLK_VALFREQ.
