drm/amd/display: Add work around to enforce TBT3 compatibility.
[Why]
According to the USB4 specification, FEC and DSC should be disabled
when a USB4 DPIA operates in TBT3 compatibility mode.
[How]
Upon detecting that a USB4 DPIA is connected to a device that is known
to operate in TBT3 mode, disable FEC and DSC support if they have been
reported by the TBT3 device.
