ASoC: dpcm: improve runtime update predictability
As it is, dpcm_runtime_update() performs the old path and new path
update of a frontend before going on to the next frontend DAI.
Depending the order of the FEs within the rtd list, the result of
the update might be different.

For example:
 * Frontend A connected to backend C, with a 48kHz playback
 * Frontend B connected to backend D, with a 44.1kHz playback
 * FE A appears before FE B in the rtd list of the card.

If we reparent BE C to FE B (disconnecting BE D):
* old path update of FE A will run first, and BE C will get hw_free()
  and shutdown()
* new path update of FE B will run after and BE C, which is stopped,
  so it will be configured at 44.1kHz, as expected

If we reparent BE D to FE A (disconnecting BE C):
* new path update of FE A will run first but since BE D is still running
  at 44.1kHz, it won't be reconfigured (no call to startup() or
  hw_params())
* old path update of FE B runs after, nothing happens
* In this case, we end up with a BE playing at 44.1kHz a stream which is
  supposed to be played at 48Khz (too slow)

To improve this situation, this patch performs all the FE old paths update
before going on to update the new paths. With this, the result should
no longer depend on the order of the FE within the card rtd list.

Please note that there might be a small performance penalty since
dpcm_process_paths() is called twice per stream direction.

ASoC: Intel: bytcr_rt5651: Add BYT_RT5651_HP_LR_SWAPPED quirk
One some models (Chuwi Vi8 Plus, Chuwi Hi8 Pro) the headphone output has
left and right swapped. This can be fixed in with special mixer settings
in the UCM profile, bit this requires these devices loading a different
UCM profile.

This commit adds a BYT_RT5651_HP_LR_SWAPPED quirk for this and postfixes
the longname with "-hp-swapped" if set, so that a different UCM profile
will be loaded.

We can safely do this without causing regressions (UCM profile not found
due to the longname change) as the UCM profiles are not in upstream
alsa-lib yet.

ASoC: Intel: bytcr_rt5651: Remove IN2 input mappings
BYT_RT5651_IN2_MAP was introduced in commit 39712db878 ("SoC: intel: byt:
Introduce new custom IN2 map"), uses in commit 2fe30129b0 ("ASoC: intel:
byt: Enable IN2 map quirk for a KIANO laptop"), only to be replaced by a
new BYT_RT5651_IN1_IN2_MAP quirk in commit ea261bd02a ("ASoC: intel:
byt: Introduce new map for dual mics") quickly afterwards, because the
KIANO laptop has 2 internal mics on IN1 and IN2 and the headset mic is
not in IN1 where the BYT_RT5651_IN2_MAP maps it, but on IN3.

Now that the KIANO quirk entry uses BYT_RT5651_IN1_IN2_MAP, there are no
users of BYT_RT5651_IN2_MAP left. This makes sense since the headset mic
seems to always be connected to IN3, so BYT_RT5651_IN2_MAP is not useful.

To deal with BYT_RT5651_IN2_MAP wrongly mapping the headset mic to IN1,
BYT_RT5651_IN2_HS_IN3_MAP was added in commit f026e06317 ("ASoC: Intel:
bytcr_rt5651: Add new IN2_HS_IN3 input map and a quirk using it"). This
was based on the assumption then some devices have the internal mic
connected to IN2 only. Further testing has shown that this is wrong and the
internal mic is always connected to IN1 and sometimes to both IN1 and IN2.

TL;DR: Both BYT_RT5651_IN2_MAP and BYT_RT5651_IN2_HS_IN3_MAP are based on
on wrong assumptions from the past and are no longer useful now, so they
can both be removed.

ASoC: Intel: bytcr_rt5651: Change default input map from in2 to in1
Further testing on all 6 model x86 tablets with a rt5651 which I have
access to for testing has shown that their single (mono) microphone is
connected to both IN1 *and* IN2.

The previous default mapping of IN2 was based on testing on the same 6
tablets, where the internal mic works fine with a mapping of IN2. But it
works fine too with a mapping of IN1.

This commit changes the default input mapping to to use IN1 instead of
IN2, to match the mapping used for the other mono devices in the DMI quirk
table. So that we need less different mappings.

The same change is made to the Chuwi Vi8 Plus quirks, which is one of the
6 models tested.

This is a preparation patch for simplifying the maps in a follow-up commit.

ASoC: cx20442: Don't ignore regulator_get() errors.
In its current shape, the driver just ignores errors returned by
regulator_get() at component_probe().  This doesn't hurt on Amstrad
Delta board as long as it registers the codec device at late_initcall,
when the regulator which depends on basic-mmio-gpio device (probed as
late as at dev_initcall) is already available.  Otherwise the driver
may end up trying to control a codec which is not powered up.

Remove that dependency on initialization order by handling the error.
If the regulator is not yet available and -ENODEV is returned, convert
it to -EPROBE_DEFER to get another chance.

ASoC: soc-pcm: DPCM cares BE channel constraint
Current DPCM is caring only FE channel configuration. Sometimes
it will be trouble if user selects channel which isn't supported
by BE.

This patch adds new .dpcm_merged_chan on struct snd_soc_dai_link.
DPCM will use FE / BE merged channel if struct snd_soc_dai_link
has it.
