ASoC: add helper to change platform name for all dailinks

To reuse the same machine drivers with Atom/SST, Skylake and SOF, we
need to change the default platform_name (or platforms->name in the
"modern" representation).

So far, this override was done with an automatic override, which was
broken by a set of changes for DT platforms related to deferred probe
handling.

This automatic override is actually not really needed, the machine
driver can already receive the platform name as a platform_data
parameter. This is used e.g. for HDaudio support where we have
different PCI aliases used for different platforms. We can reuse the
same mechanism and modify the machine drivers to override the dailinks
prior to registrating the card.

This will require additional work for SOF, but with this helper it'll
be just two lines of additional code per machine driver which is
reused, not the end of the world.

This helper can be simplified when all drivers have transitioned to
the "modern" representation of dailinks.

an EPROBE_DEFER the memory will be freed and the pointers are left

the second probe attempt which results in a use after free bug since
devm has freed the memory from the first probe attempt.

Since the intention for snd_soc_dai_link->platform is that it can be set

ASoC: Intel: bytcr_rt5651: Add quirk for PoV TAB-P1006W-232 (v1.0) tablet

Add a DMI quirk for the Point of View TAB-P1006W-232 (v1.0) tablet, this
tablet is special in a number of ways:

1) It uses the 2nd GPIO resource in the ACPI tables for jack-detect rather
then using the rt5651 codec's builtin jack-detect functionality

2) It uses the 3th GPIO resource in the ACPI tables to control the
external amplifier rather then the usual first non GpioInt resource and
the GPIO is active-low.

3) It is a BYTCR device, without a CHAN package and it uses SSP0-AIF1
rather then the default SSP0-AIF2.

4) Its internal mic is a digital mic (the first x86 rt5651 device that
I'm aware of which does this), combined with having its headset-mic
connected to IN2.

an attempt to unifify / simplify the mapping, but it was wrong.

access to a Point of View TAB-P1006W-232 (v1.0) tabler, which does use a

ASoC: ak4458: Add support for AK4497

AK4497 is a 32-bit 2ch DAC and has the same register
map as AK4458 with few exceptions:

* AK4497 has one more register at the end of register space
  DFS_READ which is a read only register that allows users
  to read FS Auto Detection mode. We currently do not use
  this register so we use the same regmap structure as for ak4458.

* Because AK4458 is an 8ch DAC there are some fields that are
  only used by AK4458 and marked as reserved for AK4497, so for
  this reason we need to have a distinct set of controls, widgets
  and routes.

Datasheet for AK4497 is at:
