Takashi Iwai 742db30c4e drm/nouveau: Add HD-audio component notifier support
This patch adds the support for the notification of HD-audio hotplug
via the already existing drm_audio_component framework.  This allows
us more reliable hotplug notification and ELD transfer without
accessing HD-audio bus; it's more efficient, and more importantly, it
works without waking up the runtime PM.

The implementation is rather simplistic: nouveau driver provides the
get_eld ops for HD-audio, and it notifies the audio hotplug via
pin_eld_notify callback upon each nv50_audio_enable() and _disable()
call.  As the HD-audio pin assignment seems corresponding to the CRTC,
the crtc->index number is passed directly as the zero-based port
number.

The bind and unbind callbacks handle the device-link so that it
assures the PM call order.

There was a version of the nouveau DDX that relied on legacy
ctx ioctls not erroring out. But that was back in time a long
ways, so offer a way to disable it now. For uapi compat with
old nouveau ddx this should be on by default, but modern distros
should consider turning it off.
