mb/intel/mtlrvp: Set USB2-10 as cnvi_wifi bluetooth companion device

To publish the Bluetooth Regulator Domain Settings under the right
ACPI device scope, the wifi generic driver requires the bluetooth
companion to be set accordingly.

This commit also updates the USB2 port 10 description and set its type
to the more appropriate `UPC_TYPE_INTERNAL' type.

BUG=b:348345301
TEST=BRDS method is added to the CNVW device and returns the data
     supplied by the SAR binary blob
