drivers/intel/usb4: Add Type-C port device attachment check
When fwupd Retimer firmware update is enabled, it needs to
differentiate the Type-C port NDA and USB/DP/TBT/USB4 DA scenarios.
This change adds support to query devices attachment. If DA, it
deasserts the Retimer power and promptly returns -1 accordingly without
impacting the flow of Retimer firmware update under NDA. Additionally,
this patch deasserts the Retimer power during error conditions.
BUG=b:212235056, 224923449, 211790542
TEST=Validated Retimer firmware update under NDA and TBT3 docks
enumeration on Type-C ports under DA.
