The MODULE_DESCRIPTION() macro is only available when including
the linux/module.h header. Apparently this is included indirectly
from sst-firmware.c in some configurations, but not in others:
sound/soc/intel/common/sst-firmware.c:1278:20: error: expected declaration specifiers or '...' before string constant
MODULE_DESCRIPTION("Intel SST Firmware Loader");
^~~~~~~~~~~~~~~~~~~~~~~~~~~
sound/soc/intel/common/sst-firmware.c:1279:16: error: expected declaration specifiers or '...' before string constant
This adds the missing include line.

The pointer dma_dev_name is assigned but never read, it is redundant
and can therefore be removed.

The recent commit [a92ea59b74: ASoC: Intel: sst: only select
sst-firmware when DW DMAC is built-in] introduced more strict kconfig
dependency (depends on DW_DMAC_CORE=y) for avoiding the build failures
due to dependency messes in intel-sst. This makes, however, it
impossible to use this driver with the modularized systems,
i.e. typically on Linux distros.
The problem addressed in the commit above is that sst_dsp_new() and
sst_dsp_free() includes the firmware init / finish that call dw_*()
functions. Thus building it as built-in with DW_DMAC_CORE module
results in the missing symbols.
However, these sst_dsp functions are basically called only from the
drivers that depend on DW_DMAC_CORE already. That is, once when these
functions are split out, the rest can be independent from dw stuff.
This patch attempts to solve the issue by the following:
- Split sst-dsp stuff into two modules: snd-soc-sst-dsp and
snd-soc-sst-firmware.
- Move sst_dsp_new() and sst_dsp_free() to the latter module so that
the former module can be independent from DW_DMAC_CORE.
- Add a new kconfig SND_SOC_INTEL_SST_FIRMWARE to select the latter
module by machine drivers.
One only remaining pitfall is that each machine driver has to select
SND_SOC_INTEL_SST_FIRMWARE carefully depending on DW_DMAC_CORE.
This can't be done cleanly due to the restriction of the current
kbuild.

We pass struct dw_dma_chip to dw_dma_probe() anyway, thus we may use it to
pass a platform data as well.
While here, constify the source of the platform data.

sst_memcpy32() only copied bytes/4 32bits, which means it dropped
the remaining bytes%4 bytes wrongly.
Here add copying those missing bytes, first to a 32bits tmp, and
then write the tmp to 32bits iomem.

Instead of hardconding a platform data for dw_dmac let's use it's own
