Disable build on non X86 architectures except for compile testing. This fixes
the following build errors on PPC and adds an option for testing the build on other
architectures as suggested by Mark Brown :-

Initial implementation of this driver focused only matching SST ACPI ID
with single machine driver and same firmware file per platform. It was known
restriction to be improved incrementally.
This patch is now changing this that SST ACPI ID refers purely to platform
specific data which refers to machine drivers on this platform, not vice
versa.
Matching machine driver is found by looking at ACPI ID which would best
match with the driver. Typically this would be the ACPI ID of audio codec
but is not tied to it.
This patch also changes that DSP firmware name is machine not platform
specific.

We originally thought to request SST audio DSP firmware during the SST
platform driver initialization. However plain request_firmware doesn't
work in driver probe paths if userspace is not ready to handle it. For
instance when drivers are built-in.
Implementing asynchronous firmware request in SST platform driver
initialization complicates code needlessly since it anyway will fail if
firmware is missing.
This is more simple to handle by requesting firmware asynchronously in
sst_acpi_probe() and register SST platform only after firmware is loaded.

Provide services for Intel SST drivers to load SST modular firmware.
SST Firmware can be made up of several modules. These modules can exist
within any of the compatible SST memory blocks. Provide a generic memory
block and firmware module manager that can be used with any SST firmware
and core.

Most of the SST devices will be exposed as ACPI devices. It makes sense to
avoid duplication of the driver enumeration logic and concentrate the functionality
into a single ACPI SST enumeration file.
Idea of this loader is to parse data we get from ACPI and to be able to load
needed other SST drivers and ASoC machine driver runtime based on single
ACPI ID what BIOS gives to us.

Add support for Intel Smart Sound Technology (SST) audio DSPs.
This driver provides the low level IO, reset, boot and IRQ management
for Intel audio DSPs. These files make up the low level part of the SST
audio driver stack and will be used by many Intel SST cores like
Haswell, Broadwell and Baytrail.
SST DSPs expose a memory mapped region (shim) for config and control.
The shim layout is mostly shared without much modification across cores
and this driver provides a uniform API to access the shim and to enable
basic shim functions. It also provides functionality to abstract some shim
functions for cores with different shim features.

In order to differentiate the different Intel SST audio core drivers we
need to rename the current drivers with a mfld prefix. This also includes
renaming in the Makefile and Kconfig

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.
