package/busybox: support automatic module loading with mdev
A recently discussed on the mailing list:
http://lists.busybox.net/pipermail/buildroot/2016-February/154189.html
Our mdev configuration currently doesn't handle module loading. Fix that by:
- Telling mdev to run modprobe on hotplug events providing MODALIAS
- Adjust the init script to handle coldplug modalias events (E.G. modules
for which the devices were already present before mdev was added as the
hotplug handler). mdev -s should arguable handle this, but it doesn't.
