This series of patches reads either pixel rate or
TMDS clock rate from DPCD. Pixel rate is defined
for DP to VGA dongles and TMDS clock rate for others
except wireless dongle. The mode that requires either
higher pixel rate or TMDS clock rate are filtered out
during the mode validity check.

Read TMDS clock rate from DPCD for HDMI to filter out
modes that might require higher TMDS clock rate than
supported.
