Khem Raj 0aa8f592df busybox: Run mdev as daemon 
When busybox is used for device management, kernel needs to support
older/obsolete mechanism via CONFIG_UEVENT_HELPER and
CONFIG_UEVENT_HELPER_PATH to enable /proc/sys/kernel/hotplug but this
would require kernel defconfig change and will always be needed when
mdev is used, intead run it in daemon mode

Update mdev init script to run mdev in daemon mode
