soc/intel/meteorlake: Correctly set Usb4CmMode

The ACPI is adjusted based on SOFTWARE_CONNECTION_MANAGER, so set
the UPD to match this to avoid the connection type being mismatched.

If it's mismatched, the TBT port will timeout.

TEST=Boot starbook/rpl and check TBT 4 dock is correctly identified.
