On newer SoCs the location of the slot width select and sample
resolution are different and also there is a bigger range of
support.

For the current supported rates then an offset is required.

On the original i2s block the channel mapping and selection were
configured for stereo audio by default: This is not the case with
the newer SoCs and they are also located at different offsets.

To support the newer SoC then regmap fields have been added to the
quirks and these are initialised to their correct settings during
probing.

Commit a53e35db ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Some SoCs have a reset line that must be asserted/deasserted.
This patch adds a quirk to handle the new compatible
"allwinner,sun6i-a31-i2s" which will deassert the reset
line on probe function and assert it on remove's one.

This new compatible is useful in case of A33 codec driver, for example.

As done previously for sun4i-codec, the DMA maxburst of 4
is not supported by every SoCs so the DMA controller engine
returns "unsupported value".

As a maxburst of 8 is supported by all variants, this patch
increases it to 8.

In our i2s driver, we were previously trying to guess which oversample the
user wanted to use by looking at the rate and trying to max it.

However, the cards, and especially simple-card with its mclk-fs property
will already provide the expected oversample ratio by using the set_sysclk
callback.

We can thus implement it and remove the logic to deal with the runtime
guess.
