ACPICA: Add SoundWire File Table (SWFT) signature

Browse source

The File Download (FDL) process of SoundWire Class Audio (SDCA) driver,
which provides code/data which may be required by an SDCA device,
utilizes SWFT to obtain that code/data. There is a single SWFT for the
system, and SWFT can contain multiple files (information about the file
as well as its binary contents). The SWFT has a standard ACPI Descriptor
Table Header, followed by SoundWire File definitions as described in
Discovery and Configuration (DisCo) Specification for SoundWire®
