Teach btusb to recognize another IMC Networks / Realtek RTL8851BE
Bluetooth radio variant.
Without BTUSB_REALTEK, the device enumerates and HCI comes up, but
btrtl never loads rtl8851bu_fw.bin, so discovery finds no devices.

Tested on Dell Precision 7820 (Fedora 44, kernel 7.2.4) with the

v2: Wrap long dmesg line in the commit message so checkpatch/gitlint
stay within the 75/80 character limits.
