The SOF-ACPI driver is backwards from the normal Linux model, it has a generic driver that knows about all the specific drivers, as opposed to having hardware specific drivers that link against a common framework.
This requires ugly Kconfig magic and leads to missed dependencies as seen in this link error:
arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_acpi_probe': sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe'
Change it to use the normal probe order of starting with a specific device in a driver, turning the sof-acpi-dev.c driver into a library.

There were a couple of build failures introduced by this version. I have one that does build now, and can post that if others think this is the direction they want to go.
