Support for RTL88x2BU WiFi driver

Hello, i managed to compile RTL88x2BU WiFi driver on my Odroid XU4 (without changing settings).
I was able to connect WiFi and host APs without any issue, so the driver was very stable on my testing and use the last weeks.
Using “ARM_RPI y” flags worked aswell.

Would like it to be included into CoreELEC, because want to use it on my Odroid N2 Kodi system.
