DPCM driver is recommended for BYT, CHT based platforms, so if
CONFIG_SND_SST_IPC_ACPI is selected then don't compile the BYT
Device IDs in common ACPI driver to avoid probe conflicts.

The ACPI match module is common to all three drivers, HSW, SKL
and Atom-DPCM driver. But Atom-DPCM driver does not use common
sst code so we cannot include the common SST module in Atom-DPCM
driver.

So the solution is to have a independent sst-match-acpi module
which helps in matching for all the three drivers. Now all driver
can be inbuilt in a single image

This patch really fixes the regression introduced by the
commit 95f09801 ("ASoC: Intel: Move apci find machine routines")

sst_memcpy32() only copied bytes/4 32bits, which means it dropped

Here add copying those missing bytes, first to a 32bits tmp, and

The previous commit ef3e199a ("ASoC: Intel: sst: only use
sst-firmware when DW DMAC is available") does not fix the 0day
building errors thoroughly:

   sound/built-in.o: In function 'dw_dma_remove'
   sound/built-in.o: In function 'dw_dma_probe'

Here we fallback to select sst-firmware only when DW DMAC
is built-in selected. We may need to refactor sst common
driver and split DW related codes to platform driver, but
ATM, this fallback may be the smallest fix.

Please be noticed that after applying this patch, we may
need select DW DMAC manually in DMA driver menu, before
we can prompt and select HSW/BDW and old BYT machines.

Currentlly, we use Synopsys DesignWare DMA Controller for
baytrail/haswell/broadwell ADSP firmware loading, but for
skylake, we don't use it, compiling sst-firmware.c may
introduce error when CONFIG_DW_DMAC_CORE is not enabled:

    sound/built-in.o: In function `sst_dma_new':
    (.text+0xd7b38): undefined reference to `dw_dma_probe'
    sound/built-in.o: In function `sst_dma_free':
    (.text+0xd7c0a): undefined reference to `dw_dma_remove'

Here we only compile sst-firmware when CONFIG_DW_DMAC_CORE
is selected, to fix the linking error issue.
