Aicsemi aic8800 Wi-Fi driver

The code placed under src folder is the unmodified driver release directly from Aicsemi, the wireless chip vendor.

Radxa did not develop this software, and will not support its usage on other hardware or Linux kernels.

We do accept PRs to fix issues with unsupported platforms, as long as the necessary changes are placed under debian/patches to not interfere with future code upgrades.
