* Add Realtek RTL8812AU out-of-tree driver
This adds support for Realtek RTL8812AU devices such as the Hardkernel
WiFi Module 5A (with the RTL8811AU chipset, supported by this driver as
well). This patch uses Realtek driver 5.9.3.2 which has been made to
compile up to Linux 5.10.
Note: This driver does not seem to support 5GHz networks! But it seems
the only driver which supports the RTL8811AU chipset and also works with
recent mainline drivers...
* Enable RTL8812AU driver for Hardkernel modules
The WiFi Module 5A comes with a RTL8811AU chipset. Enable the driver for
all Hardkernel modules.
