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.
