drm/i915/cx0: program DDI_CLK_VALFREQ with DDI clock frequency
DDI_CLK_VALFREQ is programmed with the port clock, which for DP is the
symbol clock computed assuming 8b/10b encoding (link_rate / 10). For
DP 128b/132b (UHBR) rates and for HDMI FRL the port clock needs to
be modfied.
DDI_CLK_VALFREQ does not have any functional impact on H/w, it
only records the frequency S/w intends to set.
Use intel_ddi_link_symbol_clock() to write the correct DDI clock in
kHz.
