Adding a kernel module based USB wifi driver. There is no official
version of this driver that works properly on ARM and with newer USB
WiFi cards. This driver version builds module 8821au and is based on a
kernel module release from ASUS with various fixes integrated in.

I've switched to use ulli-kroll's branch of rtl8821au. While it's based
on an older vendor version, it has binary firmware and around ~1800
commits of work to improve the driver. I think this work is probably
more valuable than the vendor's updates.

+Comment out the hardcoded debug defines. If extra debug is needed, we can add it
+as a define in the make flags.
