As we are now passing the filter data as pointers to the drivers,
we can take the final step and also pass the filter function the
same way. I'm keeping this change separate, as there it's less
obvious that this is a net win.
Upsides of this are:
- The ASoC drivers are completely independent from the DMA engine
implementation, which simplifies the Kconfig logic and in theory
allows the same sound drivers to be built in a kernel that supports
different kinds of dmaengine drivers.
- Consistency with other subsystems and drivers
On the other hand, we have a few downsides:
- The s3c24xx-dma driver now needs to be built-in for the ac97 platform
device to be instantiated on s3c2440.
- samsung_dmaengine_pcm_config cannot be marked 'const' any more
because the filter function pointer needs to be set at runtime.
This is safe as long we don't have multiple different DMA engines
in thet same system at runtime, but is nonetheless ugly.

This is a minor cleanup to make the s3c2412-i2s and s3c24xx-i2s
drivers independent of the mach/dma.h header file and to allow
removing the dependency on the specific dmaengine driver in the
next patch.
As a side not, only the s3c24xx-i2s driver seems to still be
used, while the definition of the s3c2412-i2s platform device was
removed in commit 6d259a25b5 ("ARM: SAMSUNG: use static
declaration when it is not used in other files") after it had
never been referenced since its introduction in f0fba2ad1b
("ASoC: multi-component - ASoC Multi-Component Support").
Apparently it should have been used by mach-jive.c, but that
never happened. My patch at this point leaves the current state
unchanged, we can decide whether to fix or delete the jive
driver and s3c2412-i2s another time.

ARM64 allmodconfig produces a bunch of warnings when building the
samsung ASoC code:
sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data':
sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
playback_data->filter_data = (void *)playback->channel;
sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
capture_data->filter_data = (void *)capture->channel;
We could easily shut up the warning by adding an intermediate cast,
but there is a bigger underlying problem: The use of IORESOURCE_DMA
to pass data from platform code to device drivers is dubious to start
with, as what we really want is a pointer that can be passed into
a filter function.
Note that on s3c64xx, the pl08x DMA data is already a pointer, but
gets cast to resource_size_t so we can pass it as a resource, and it
then gets converted back to a pointer. In contrast, the data we pass
for s3c24xx is an index into a device specific table, and we artificially
convert that into a pointer for the filter function.

Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().
This change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.
The patch was generated with the following coccinelle semantic patch:
