wait host devs in base module

each dev in host_devs[] should be waited in initqueue to make sure they
are oneline before initqueue finish.

Add a new wait_host_devs.sh in base module to make this a generic thing.
Because all the devs in fstab lines are also added to host_devs, so no need
do same wait in fstab-sys module anymore.

[v2->v3]: do not add slave devices to host_devs
          wait for persistent dev name in initramfs
