On certain platforms, Display HDMI HDA codec was not going to sleep state
after the use when links are powered down after turning off the display
power. As per the HW recommendation, links are powered down before turning
off the display power to ensure that the codec goes to sleep state.

This patch was updated from an earlier version submitted upstream [1]
which conflicted with the changes merged for HDaudio codec support
with the Intel DSP.

This is the final step for more generic support of DRM audio
component.  The generic audio component code is now moved to its own
file, and the symbols are renamed from snd_hac_i915_* to
snd_hdac_acomp_*, respectively.  The generic code is enabled via the
new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is
kept as the super-class.

Along with the split, three new callbacks are added to audio_ops:
pin2port is for providing the conversion between the pin number and
the widget id, and master_bind/master_unbin are called at binding /
unbinding the master component, respectively.  All these are optional,
but used in i915 implementation and also other later implementations.

A note about the new snd_hdac_acomp_init() function: there is a slight
difference between this and the old snd_hdac_i915_init().  The latter
(still) synchronizes with the master component binding, i.e. it
assures that the relevant DRM component gets bound when it returns, or
gives a negative error.  Meanwhile the new function doesn't
synchronize but just leaves as is.  It's the responsibility by the
caller's side to synchronize, or the caller may accept the
asynchronous binding on the fly.

v1->v2: Fix missing NULL check in master_bind/unbind
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The HD-audio i915 binding code contains a single pointer, hdac_acomp,
for allowing the access to audio component from the master bind/unbind
callbacks.  This was needed because the callbacks pass only the device
pointer and we can't guarantee the object type assigned to the drvdata
(which is free for each controller driver implementation).
And this implementation will be a problem if we support multiple
components for different DRM drivers, not only i915.

As a solution, allocate the audio component object via devres and
associate it with the given device, so that the component callbacks
can refer to it via devres_find().

The removal of the object is still done half-manually via
devres_destroy() to make the code consistent (although it may work
without the explicit call).

Also, the snd_hda_i915_register_notifier() had the reference to
hdac_acomp as well.  In this patch, the corresponding code is removed
by passing hdac_bus object to the function, too.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

For allowing other drivers to use the DRM audio component, rename the
i915_audio_component_* with drm_audio_component_*, and split the
generic part into drm_audio_component.h.  The i915 specific stuff
remains in struct i915_audio_component, which contains
drm_audio_component as the base.

The license of drm_audio_component.h is kept to MIT as same as the the
original i915_component.h.

This is a preliminary change for further development, and no
functional changes by this patch itself, merely code-split and
renames.

v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915
        argument in drm_audio_component.h

waits until actual state reaches target state. Thus ensuring power
