[Buildroot] [git commit] configs/amarula_a64_relic: add WiFi support

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=5e01e9442d548e4e362595891f67440e4f6b30e3
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Amarula A64-Relic board has AP6330 WiFi/BT combo, but does
not have ethernet port. So it makes sense to enable wireless
networking by default:
- add broadcom wireless firmware package to image
- add basic wireless tools to image
- add rootfs overlay with proper NVRAM file for on-board AP6330 chip
- add mdev to image to enable module autoloading
- update readme.txt to test wifi
