ASoC: Remove dev_err() usage after platform_get_irq()
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

 Most of fixes are targeted for the newly merged SOF (Sound Open

 Other than that, there are a few regression fixes for the recent
 ASoC core changes and HD-audio quirk, as well as a couple of

ASoC: sun4i-i2s: Change SR and WSS computation
The current computation for the SR (sample resolution) and the WSS (word
slot size) register parameters is based on a switch returning the matching
parameters for a given params width.

Later SoCs (A83t, H3, A64) changed that calculation, which was loosely the
same with an offset. Therefore, an offset was added to adjust those
parameters.

However, the calculation is a bit less trivial than initially thought.
Indeed, while we assumed that SR and WSS were always the same, on older
SoCs, SR will max at 24 (since those SoCs do not support 32 bits formats),
but the word size can be 32.

Newer SoCs can also support a much larger range (8 bits to 32 bits, by
increments of 4) of size than the older SoCs could.

Finally, the A64 and A83t were never adjusted to have that offset in the
first place, and were therefore broken from that point of view.

In order to fix all those issues, let's introduce two functions, get_wss
and get_sr, with their respective implementations for all the SoCs
supported so far.

ASoC: sun4i-i2s: Show detailed error when DAI configuration callbacks fail
When any of the DAI hardware configuration callbacks (.hw_param,
.set_fmt, .set_sysclk) fails, there is no explanation about why it
failed. This is particularly confusing for .hw_param, which covers
many parameters of the DAI. Telling the users what parameter isn't
supported, and what the requested value was goes a long way for
developers trying to combine sun4i-i2s with external codecs.

This patch adds dev_err calls explaining what isn't supported or
failed, and what the value was. sun4i_i2s_set_clk_rate()'s first
parameter was changed to a struct snd_soc_dai *dai, so we can
get the underlying device.

ASoC: sun4i-i2s: Add support for A83T
The I2S controller in the A83T is mostly compatible with the one found
in earlier SoCs such as the A20 and A31. While the documents publicly
available for the A83T do not cover this hardware, the officially
released BSP kernel does have register definitions for it. These were
matched against the A20 user manual. The only difference is the TX FIFO
and interrupt status registers have been swapped around, like what we
have seen with the SPDIF controller.

This patch adds support for this hardware.
