ASoC: fsl: Fix PM disable depth imbalance in fsl_easrc_probe
The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by calling
pm_runtime_disable when error returns.

ASoC: fsl: fsl_easrc: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: fsl_easrc: Don't use devm_regmap_init_mmio_clk
When there is power domain bind with mem clock,

The call flow:
devm_regmap_init_mmio_clk
  - clk_prepare()
      - clk_pm_runtime_get()

cause the power domain of clock always be enabled after
regmap_init(). which impact the power consumption.

So use devm_regmap_init_mmio instead of
devm_regmap_init_mmio_clk,but explicitly enable
clock when it is used.

ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32()
We had read/write function for Codec, Platform, etc,
but these has been merged into snd_soc_component_read/write().

Internally, it is using regmap or driver function.
In read case, each styles are like below

regmap
	ret = regmap_read(..., reg, &val);

driver function
	val = xxx->read(..., reg);

Because of this kind of different style, to keep same read style,
when we merged each read function into snd_soc_component_read(),
we created snd_soc_component_read32(), like below.
commit 738b49efe6 ("ASoC: add snd_soc_component_read32")

(1)	val = snd_soc_component_read32(component, reg);

(2)	ret = snd_soc_component_read(component, reg, &val);

Many drivers are using snd_soc_component_read32(), and
some drivers are using snd_soc_component_read() today.

In generally, we don't check read function successes,
because, we will have many other issues at initial timing
if read function didn't work.

Now we can use soc_component_err() when error case.
This means, it is easy to notice if error occurred.

This patch aggressively merge snd_soc_component_read() and _read32(),
and makes snd_soc_component_read/write() as generally style.

This patch do
	1) merge snd_soc_component_read() and snd_soc_component_read32()
	2) it uses soc_component_err() when error case (easy to notice)
	3) keeps read32 for now by #define
	4) update snd_soc_component_read() for all drivers

Because _read() user drivers are not too many, this patch changes
all user drivers.

ASoC: fsl_easrc: mark PM functions __maybe_unused
ifdefs are hard, and in this driver the suspend/resume functions are
the only callers of some other helpers that trigger a harmless warning
when CONFIG_PM is disabled:

sound/soc/fsl/fsl_easrc.c:1807:12: warning: 'fsl_easrc_get_firmware' defined but not used [-Wunused-function]
 1807 | static int fsl_easrc_get_firmware(struct fsl_asrc *easrc)
      |            ^~~~~~~~~~~~~~~~~~~~~~
sound/soc/fsl/fsl_easrc.c:303:12: warning: 'fsl_easrc_resampler_config' defined but not used [-Wunused-function]
  303 | static int fsl_easrc_resampler_config(struct fsl_asrc *easrc)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~

Remove the #ifdef and just mark the callers as __maybe_unused to
suppress the warnings altogether.

ASoC: fsl_easrc: Check for null pointer before dereferencing "ctx" in fsl_easrc_hw_free()
The patch 955ac62405: "ASoC: fsl_easrc: Add EASRC ASoC CPU DAI
drivers" from Apr 16, 2020, leads to the following Smatch complaint:

sound/soc/fsl/fsl_easrc.c:1529 fsl_easrc_hw_free()
warn: variable dereferenced before check 'ctx' (see line 1527)

sound/soc/fsl/fsl_easrc.c
  1526          struct fsl_asrc_pair *ctx = runtime->private_data;
  1527          struct fsl_easrc_ctx_priv *ctx_priv = ctx->private;
                                                      ^^^^^
Dereference

  1528
  1529          if (ctx && (ctx_priv->ctx_streams & BIT(substream->stream))) {
                    ^^^
This check is too late, to prevent a NULL dereference.

  1530                  ctx_priv->ctx_streams &= ~BIT(substream->stream);
  1531                  fsl_easrc_release_context(ctx);

ASoC: fsl_easrc: Add EASRC ASoC CPU DAI drivers
EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module
found on i.MX8MN. It is different with old ASRC module.

The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control
- Simultaneous processing of up to 32 audio channels
- Programmable filter charachteristics for each context
- 32, 24, 20, and 16-bit fixed point audio sample support
- 32-bit floating point audio sample support
- 8kHz to 384kHz sample rate
- 1/16 to 8x sample rate conversion ratio
