ASoC: Switch back to struct platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

ASoC: sunxi: sun4i-i2s: fix LRCLK polarity in i2s mode

This fixes the LRCLK polarity for sun8i-h3 and sun50i-h6 in i2s mode
which was wrongly inverted.

The LRCLK was being set in reversed logic compared to the DAI format:
inverted LRCLK for SND_SOC_DAIFMT_IB_NF and SND_SOC_DAIFMT_NB_NF; normal
LRCLK for SND_SOC_DAIFMT_IB_IF and SND_SOC_DAIFMT_NB_IF. Such reversed
logic applies properly for DSP_A, DSP_B, LEFT_J and RIGHT_J modes but
not for I2S mode, for which the LRCLK signal results reversed to what
expected on the bus. The issue is due to a misinterpretation of the
LRCLK polarity bit of the H3 and H6 i2s controllers. Such bit in this
case does not mean "0 => normal" or "1 => inverted" according to the
expected bus operation, but it means "0 => frame starts on low edge" and
"1 => frame starts on high edge" (from the User Manuals).

This commit fixes the LRCLK polarity by setting the LRCLK polarity bit
according to the selected bus mode and renames the LRCLK polarity bit
definition to avoid further confusion.

ASoC: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ASoC: sunxi: sun4i-i2s: 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: sun4i-i2s: Update registers for more channels

H6 expands the number of channels in each direction to 16, so the slot
number fields need to be expanded from 3 to 4 bits each.

R329/D1 expand that further by allowing each of the 16 slots to map to
any of 4 data pins. For TX, the configuration of each pin is
independent, so there is a copy of the mapping registers for each pin.
For RX, each of the 16 slots can map to only one pin, so the registers
were changed to add the pin selection inline with the channel mapping.

On the newer SoCs such as the H3 and A64 this is set by default

and A20 SoCs that this driver was developed on had a default
setting where it padded the audio gain with zeros.

This isn't a problem while we have only support for 16bit audio
but with larger sample resolution rates in the pipeline then SEXT
bits should be cleared so that they also pad at the LSB. Without
this the audio gets distorted.

Set sign extend sample for all the sunxi generations even if they
are not affected. This will keep consistency and avoid relying on
default.

ASoC: sun4i-i2s: Change set_chan_cfg() params

As slots and slot_width can be set manually using set_tdm().
These values are then kept in sun4i_i2s struct.
So we need to check if these values are set or not.

This is not done actually and will trigger a bug.
For example, if we set to the simple soundcard in the device-tree
dai-tdm-slot-width = <32> and then start a stream using S16_LE,
currently we would calculate BCLK for 32-bit slots, but program
lrck_period for 16-bit slots, making the sample rate double what we
expected.

To fix this, we need to check if these values are set or not but as
this logic is already done by the caller. Avoid duplicating this
logic and just pass the required values as params to set_chan_cfg().
