ASoC: Intel: Boards: Fix NULL pointer deref in BYT/CHT boards

Since commit 13f58267cda3 ("ASoC: soc.h: don't create dummy Component
via COMP_DUMMY()") dummy snd_soc_dai_link.codecs entries no longer
have a name set.

This means that when looking for the codec dai_link the machine
driver can no longer unconditionally run strcmp() on
snd_soc_dai_link.codecs[0].name since this may now be NULL.

Add a check for snd_soc_dai_link.codecs[0].name being NULL to all
BYT/CHT machine drivers to avoid NULL pointer dereferences in
their probe() methods.

Fixes: 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()")

ASoC: Intel: bytcht_da7213: Replace open coded acpi_dev_put()

Instead of calling put_device(&adev->dev) where adev is a pointer
to an ACPI device, use specific call, i.e. acpi_dev_put().

Also move it out of the conditional to make it more visible in case
some other code will be added which may use that pointer. We need
to keep a reference as long as we use the pointer.

ASoC: Intel: byt/cht: set pm ops dynamically

The Atom/SST driver does not rely on ASoC power management, but the
SOF driver does. Rather than using a hard-coded build-time assignment,
we can set this pm_ops dynamically depending on what the parent
is. That will remove the last build-time dependency and allow for
coexistence of both SST and SOF drivers for Baytrail/Cherrytrail.

ASoC: Intel: byt*: simplify card names for SOF uses

Blindly adding an sof- prefix to the card name is not user friendly
and causes UCM issues with a driver name truncated to 16 characters.

Simplify to use "sof-bytcht <codec_name>" pattern for all byt* machine
drivers. The sof- prefix is added by the core. A generic "SOF" driver
name is used, and UCMv2 will detect the configuration for this driver
by testing the card name.

Legacy uses are unmodified.

ASoC: Intel: boards: remove hard-coded compressed dailinks

The hard-coded compressed dailinks are not supported using
publicly-available firmwares, which creates unnecessary user
confusion [1]. Even if the firmware was available, the mainline
code does not have the required .dynamic=1 and .dpcm_playback=1
fields so probably never worked as is, and last and they conflict
with topology-defined streams.

Remove them and move on. This can be re-enabled with SOF later
in a more flexible manner.
