Subject: [PATCH] Changes required for ARM64_RPI builds to work

This makes the instructions in the main README work which suggest the following before installing for a dkms install:

```
$ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
$ sed -i 's/CONFIG_PLATFORM_ARM64_RPI = n/CONFIG_PLATFORM_ARM64_RPI = y/g' Makefile
```

This makes building for the 3B on ubuntu/arm64 work, and should work for 3B+ in arm64 mode as well.

This should fix the bug reported here: https://github.com/aircrack-ng/rtl8812au/issues/336
