ALSA: hda - Integrate input-jack stuff into kctl-jack
Instead of managing input-jack stuff separately, call all stuff inside
the kctl-jack creation, deletion and report. The caller no longer needs
to care about input-jack.
The better integration between input-jack and kctl-jack should be done
in the upper layer in near future, but for now, it's implemented locally
for more tests.
