pkg: Add support for cold-plugged devices to init

Browse Source 
mdev only supports hot-plug, ie devices which are added
after the kernel booted. For cold-plugged devices, ie devices
present when the kernel boots, we need to modprobe the drivers
differently. The additions to rc.init does just that.
