Bluetooth: btusb: Add ASUS USB-BT600 for Realtek 8761CU
Add the vendor/product ID (0x0b05, 0x1d70) to the usb_device_id table for
the Realtek RTL8761CU-based ASUS USB-BT600 adapter. It binds via the
generic Bluetooth class today, so BTUSB_REALTEK is never set and the
rtl8761cu firmware is not loaded, leaving the controller non-functional.
With the entry the driver loads rtl_bt/rtl8761cu_fw.bin (already shipped by
linux-firmware) and the adapter works (tested: A2DP and ASHA).
Similar to commit bc597f0cc44f
("Bluetooth: btusb: Add TP-Link UB600 for Realtek 8761BUV").
