ALSA: hda - Implement headset jack functionality for some Dell hw

On some machines, there is a headset jack that can support both
headphone, headsets (of both CTIA and OMTP type) and mic-in.

On other machines, the headset jack supports headphone, headsets
(both CTIA and OMTP), but not mic-in.

This patch implements that functionality as different capture sources.

ALSA: hda - Fix headset mic support for Asus X101CH

With this patch, a TRRS headset mic cannot be successfully detected
on the Asus X101CH, and we can also distinguish between headphone
and headset automatically.

ALSA: usb-audio: disable autopm for MIDI devices

Commit 88a8516a2128 (ALSA: usbaudio: implement USB autosuspend)
introduced autopm for all USB audio/MIDI devices.  However, many MIDI
devices, such as synthesizers, do not merely transmit MIDI messages but
use their MIDI inputs to control other functions.  With autopm, these
devices would get powered down as soon as the last MIDI port device is
closed on the host.

Even some plain MIDI interfaces could get broken: they automatically
send Active Sensing messages while powered up, but as soon as these
messages cease, the receiving device would interpret this as an
accidental disconnection.

Commit f5f165418cab (ALSA: usb-audio: Fix missing autopm for MIDI input)
introduced another regression: some devices (e.g. the Roland GAIA SH-01)
are self-powered but do a reset whenever the USB interface's power state
changes.

To work around all this, just disable autopm for all USB MIDI devices.
