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).
