Description

This change makes Bluetooth work with the Orange PI 3 LTS. It's based on these commits:

https://github.com/orangepi-xunlong/orangepi-build/commit/ef22bd4b078388eab200a68384a6dff8d959dcb0 https://github.com/orangepi-xunlong/orangepi-build/commit/ed6d012459461014d41acd22316c1643ff94a127 https://github.com/orangepi-xunlong/orangepi-build/commit/7d01d1d61c99b3038601f061751a46920446f189

How Has This Been Tested?

I build focal current image and test on OPI 3 LTS. Before this change, there is no /sys/class/bluetooth. After this change I can scan bluetooth and pair with my mobile phone.

pierre@orangepi3-lts:~$ ls /sys/class/blue*
hci0
