Function sst_acpi_probe() uses plain strcpy for setting member firmware_name
of a struct intel_sst_drv from member firmware of a struct sst_machines.
Thereby the destination array has got a length of 20 byte while the source may
hold 32 byte. Since eg. commit 64b9c90b86 ("ASoC: Intel: Fix BYTCR firmware
name") increased strings from "fw_sst_0f28.bin" to "intel/fw_sst_0f28.bin"
there is an actual possibility that the 20 byte array at the end of struct
intel_sst_drv is overrun.
Thus increase the size of the destination and use the same define for both
structs. Detected by Coverity CID 1260087.

This patch add ACPI device ID and platform data for two Cherryview-based
platforms, Cherrytrail and Braswell. Also reuse mfld driver ops in sst driver.

Add the last ACPI module support which also uses core module like the PCI
part

sst_save_shim64() is defined as static in code but header is non static.
Since this is not used other than file where defined remove non static
definition

Now the SST_IPC will support both ACPI and PCI, separate into core module
and PCI module. This also move probe function into PCI module and exports
the required symbols from core module

In order to support both ACPI and PCI devices we need to use a genric device
id in driver, so change all pci_id instances to device_id

The SST driver is the missing piece in our driver stack not upstreamed,
so push it now :) This driver currently supports PCI device on Merrifield.
Future updates will bring support for ACPI device as well as future update
to PCI devices as well
In subsequent patches support is added for DSP loading using memcpy,
pcm operations and compressed ops.
