ASoC: SDCA: Add FDL library for XU entities

Browse source

Some instances of the XU Entity have a need for Files to be downloaded
from the Host. In these XUs, there is one instance of a Host to Device
(Consumer) UMP, identified by the FDL_CurrentOwner Control. FDL Library
introduced here implements the FDL flow triggered by FDL_CurrentOwner
irq, which sends a file from SoundWire File Table (SWFT) or from the
firmware directory in specific cases, to the Device FDL UMP.

Currently only Direct method of FDL is implemented.
