Bluetooth: btusb: Add VID/PID 0489:e156 for MediaTek MT7902

[Sean Wang]

Hi Кирилл,

Could you help get the USB device information from your test machine
as the following and reply to the mail?

The information in /sys/kernel/debug/usb/devices about the Bluetooth
device is listed as the below.

I will send the patch including the VID/PID
thanks
