Bluetooth: btusb: Add one more Bluetooth part for the Realtek RTL8852AE

commit 2e7b4a328ed6ea57d22853939e69bc86c560996d upstream.

This Realtek device has both wifi and BT components. The latter reports
a USB ID of 0bda:2852, which is not in the table.

BT device description in /sys/kernel/debug/usb/devices contains the following entries:
