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.

The madera driver was merged too late to catch Thomas Gleixner's cleanup
of the SPDX headers tree wide. Update the headers to match what was done
in that patch.

The Cirrus Logic Madera codecs are a family of related codecs with
extensive digital and analogue I/O, digital mixing and routing,
signal processing and programmable DSPs. This patch adds common
support code shared by all Madera codecs.
This patch also adds the pdata to the parent mfd pdata struct.
Since there is a circular build dependency it's convenient to
patch them both atomically.
