Change the firmware filename format on SoundWire systems to
directly tie it to the physical amp it applies to. This is mainly
to decouple it from the ALSA prefix strings to avoid complications
when the SoundWire machine driver starts creating dailinks based on
SDCA Disco info instead of hardcoded match tables. It also avoids
errors from having to rename firmware files from a hardware-address
to a ALSA-prefix naming for Linux publication. There are already
published firmware files for the L56 B0 silicon so that has a fallback
scheme for backward compatibility which has been separated into its
own patch on top of the main change.

We'd like to get this into 6.16 so that the L63 support starts "clean"
with this new naming and we don't have to support one kernel version
with L63 using the old naming. Unfortunately we didn't manage to get
these patches through internal review and testing before the merge
window opened.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
