Bug description:
[Impact]
Connect the 4K@60Hz monitor on WD19, the monitor can't light.
[Fix]
As per DP spec, at first check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT.
If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1, read the DP_DP13_DPCD_REV to
get the faster capability. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 0, read
DP_DPCD_REV.
[Test]
With the patches, connect 4K@60Hz monitor on WD19, the machine can output the
video to the monitor and the monitor can light.
[Regression]
low, Just get one more DPCD from the extended register, compare them and get
the faster one.
