Currently, when connecting a DAI widget to the BE CPU DAI, we overwrite
the previous connections. This worked because we only ever had 1 CPU DAI
for each rtd until now. But with multiple CPU DAI's, a new connection
between a BE CPU DAI and the DAI widget should be established without
affecting the previous connections. So, modify the loop to set the
playback/capture widget for the first BE CPU DAI that does not have a
connection established previously.

cpu-dais")

[ 560.049047] sof-audio-pci 0000:00:1f.3: firmware boot complete

Since the DSP is powered down when not in used this happens everytime

When a SoundWire link is in clock stop state, a Slave device may wake
up the Master for some events such as jack detection. The WAKEEN
interrupt will be triggered and processed by the audio pci device.
If audio device is in D3, the interrupt will be routed to PME, or
aggregated at cAVS level as interrupt when audio device is in D0. This
patch only supports D3 case, where the audio pci device will be
resumed by a PME event and the WAKEEN interrupt will be processed
after audio pci device is powered up and ROM is initialized
successfully.
The WAKEEN handling is only enabled after the first boot due to
dependencies on a shim_lock mutex being initialized.

For now we have a limited number of machine driver configurations, and
we can detect them based on the link configuration returned after
checking hardware and firmware (BIOS) configurations.
The link configuration is checked with a link_mask as well as a list
of _ADR descriptors for each link.
There is a chance that in extreme cases where the BIOS contains too
much information we would need to detect which Slave devices actually
report as 'attached'. This would be more accurate than static
table-based solutions, but it also introduces timing dependencies
since we don't know when those devices might become attached, so will
only be only be looked at if we see limitations with static methods
and the usual quirks based e.g. on DMI information.

Now that the SoundWire core supports the multi-step initialization,
call the relevant APIs.
The actual hardware enablement can be done in two places, ideally we'd
want to startup the SoundWire IP as soon as possible (while still
taking power rail dependencies into account)
However when suspend/resume is implemented, the DSP device will be
resumed first, and only when the DSP firmware is downloaded/booted
would the SoundWire child devices be resumed, so there are only
marginal benefits in starting the IP earlier for the first probe.

a kernel module parameter and a kernel option were initially
provided to configure default behaviour of SOF on Intel hardware
with commit 139c7febad ("ASoC: SOF: Intel: add support for
snd-hda-codec-hdmi").
As hdac-hdmi is already now lagging in features compared to
snd-hda-codec-hdmi, move ahead with the transition and remove
the build option to select between the two, and instead default
to snd-hda-codec-hdmi if it is enabled in kernel build.
The old behaviour of using hdac-hdmi driver can still be forced
via the kernel module parameter.

This can happen for multiple reasons:
- internal graphics is disabled on the system
- i915 driver is not enabled in kernel or it fails to init
- i915 codec reports error in HDA codec probe
- HDA codec driver probe fails
Address all these scenarios, but keep using the existing topology.
In case failures occur, HDMI PCM nodes are created, but they will
report error if application tries to use them. No ALSA mixer controls
are created. If the external HDA codec init fails as well, SOF probe
