[PATCH v2] Bluetooth: btusb: Add support for TP-Link TL-UB250

[Cris <cxs1494089474@gmail.com>]

Add USB ID 2357:0607 for TP-Link TL-UB250.

This is a Realtek RTL8761BUV based Bluetooth adapter.

Without this entry the device is picked up by the generic Bluetooth USB
class match and exposes hci0, but the Realtek setup path is not used and
rtl8761bu firmware/config are not loaded.

The controller reports Realtek Semiconductor Corporation as the
manufacturer and LMP subversion 0x8761. With this entry added, btusb
loads rtl_bt/rtl8761bu_fw.bin and rtl_bt/rtl8761bu_config.bin
successfully.

Relevant part of /sys/kernel/debug/usb/devices:

T:  Bus=01 Lev=02 Prnt=06 Port=00 Cnt=01 Dev#=  9 Spd=12   MxCh= 0
D:  Ver= 1.10 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=2357 ProdID=0607 Rev= 2.00
S:  Product=TP-Link TL-UB250 Adapter
C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=500mA
I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb
I:* If#= 1 Alt= 0 #EPs= 2 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb

Use the same flags as the existing TP-Link 2357:0604 entry.
