The addition of a managed version of snd_soc_register_dai() is to fix resource leaks. There's also a few new device IDs for x86 systems.

On other platforms, we used a single Kconfig option, so we should follow the same trend by merging the two cases in a backwards compatible way. The backwards compatibility is handled by overloading the COMETLAKE_LP kconfig as COMETLAKE. In practice we've never seen a case where COMETLAKE_H is not selected along with COMETLAKE_LP, so keeping one of the two is enough.

snd_hdac_bus_queue_event() and snd_hdac_bus_exec_verb() are used only
internally in HD-audio core.  Let's drop the exports and move the
declarations into local.h.

ALSA: hda: Fix potential race in unsol event handler

The unsol event handling code has a loop retrieving the read/write
indices and the arrays without locking while the append to the array
may happen concurrently.  This may lead to some inconsistency.
Although there hasn't been any proof of this bad results, it's still
safer to protect the racy accesses.

This patch adds the spinlock protection around the unsol handling loop
for addressing it.  Here we take bus->reg_lock as the writer side
snd_hdac_bus_queue_event() is also protected by that lock.

Stripe control programming is governed by following formula, which is
referenced from the HD Audio specification(Revision 1.0a).
  { ((num_channels * bits_per_sample) / number of SDOs) >= 8 }

Currently above is implemented in snd_hdac_get_stream_stripe_ctl().
This patch introduces a structure member to store the default factor
of '8'. If any HW wants to use a different value, this member can be
easily updated.
