This patch update physicals DAI link config to ABI v5:
- Define the types and ABI struct for runtime supported hardware configs
e.g. audio hardware formats. The default HW config ID will help topology
to find the DAI format to set on init. Topology provides this as a
fallback if such HW settings are not available in ACPI or device tree,
to avoid hard code in drivers. It's only for config items that can be
programmed by SW or FW, not for physical things like link connections
or GPIO used for HP etc.
- Add flags. The flags will be used to configure an existing physical
links.
- Add private data. The private data is reserved for future extension.
- Add name and stream name to physical DAI links. Kernel can also use name
and stream name to find an existing physical link and configure it.
Kernel can handle the ABI update in a backward compatible way via patch
'ASoC: topology: Add support to configure existing physical DAI links'.
