This patch adds support for the RTL8761B USB Bluetooth dongle.
When I got the RTL8761B dongle, I see it is actually recognised as
RTL8761A in my system (5.5.15-200.fc31.x86_64 on Fedora). And the
userspace cannot detect bluetooth devices in such situation.

Icenowy Zheng offered great help by identifying the firmware
from the vendor-provided Windows driver. After applying this patch along
with the firmware I am able to use this dongle.
Note, I don't have RTL8761A device, so I would appreciate if someone
can help test in case this patch breaks RTL8761A.
The RTL8761A information is from the following Github issue
