[PATCH] Bluetooth: btusb: add Realtek RTL8852CE device ID 0x0852

[Christos Longros]

Add the native Realtek vendor device ID (0bda:0852) for the RTL8852CE
Bluetooth radio to the btusb device table.

Without this entry the device is matched only by the generic Bluetooth
class rule (USB_INTERFACE_INFO 0xe0/0x01/0x01), which means btusb
binds but without the BTUSB_REALTEK flag.  This skips Realtek-specific
firmware loading, event handling, and wideband speech support.

Tested on a Gigabyte B650 Gaming X AX V2 with the onboard RTL8852CE
combo WiFi/BT card (USB ID 0bda:0852).
