from aDSP, handling interrupt, sending different types of messages etc

For SKL IPC, we have some register bits with attribute RWC. So we need to
force update them. Add helper to force update this type of registers bits.

Currently in Intel SST driver, some similar IPC/mailbox processing
code are used in different platforms (e.g. in baytrail/broadwell).
This patch extracts the common code and creates new files
(sst-ipc.c/sst-ipc.h) to contain the common code and provide the generic
APIs for IPC/mailbox processing.
