component has io_mutex, but it had been used at
snd_soc_component_update_bits_legacy() only which does read and write.

	static int snd_soc_component_update_bits_legacy(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		...
		old = snd_soc_component_read(...);
		...
		ret = snd_soc_component_write(...);
		...
=>		mutex_unlock(&component->io_mutex);
		...
	}

It is pointless if it is not used with both read and write functions.
This patch uses io_mutex correctly with read/write.
Here, xxx_no_lock() is local functions.

	static int snd_soc_component_read(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		val = soc_component_read_no_lock(...);

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 738b49ef ("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.

Merge series "ASoC: Intel: Add KeemBay ASoC platform driver" from Sia Jee Heng <jee.heng.sia@intel.com>:

The below series of patches support the KeemBay ASoC platform driver.
The platform driver initialize the i2s to capture and playback the
pcm data on the ARM. The i2s is running in polling mode.

There is no DSP in the KeemBay SoC. Users are rely on the Gstreamer plugin
to perform Audio preprocessing.

Audio graph card is used to connect the platform driver with the
tlv320aic3204 codec.

Change History:
v5:
- Remove OF dependency from Kconfig as OF is shifted to audio graph card.

v4:
- Reduce if-otology at the tx/rx function.
- Fix indentation.
- specify .rate directly

v3:
- Adjusted header format.
- Use Audio graph card instead of custom sound card.
- Use if-else instead of conditional operator.
- Enabled .set_fmt to configure master clock.

v2:
- Corrected I2S naming for DT binding.

v1:
- Initial version.

Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.
