Add support of xbox wireless adapter for xbox controller

Hi guys,

Recently I'm trying to let xbox wireless adapter (dongle) work on libreelec 12.0, and now it works on x86 generic version.

I compile medusalix/xow project and install it to libreelec, it just works.

Here are the support packs:

forum.libreelec.tv/core/attachment/10494/

Install procedure:

1. Make sure no any dongle are inserted to your libreelec box

2. copy the support pack to your libreelec os

3. decompress it to the root folder ( unzip xow-libreelec.zip -d / )

4. reboot your libreelec

5.…
