Add a generic way to create jack inputs for auxiliary jack detection

The simple-card can be used as combining card driver to add the jacks,
no new one is required.
Create a jack (for input-events) for jack devices in the auxiliary
device list (aux_devs). A device which returns a valid value on
get_jack_type counts as jack device; set_jack is required
to add the jack to the device.

Given that everyone is really supposed to be using the
audio-graph cards for new systems this should be hooked up there
too.
Hello,
Yes auxiliary devices are very useful, e.g. for GPIO. I can make a patch
for audio-graph-card.c to add it.
Best Regards
