Add a SoundWire machine-driver match entry for boards with an RT713
(SDCA "VB" jack/dmic variant) on link 0 and two RT1320 speaker amps
sharing link 2 (distinguished by unique_id 0/1, left/right).
This exact codec pairing is already supported on Panther Lake
(ptl_sdw_rt713_vb_l2_rt1320_l13) and Lunar Lake
(lnl_sdw_rt713_vb_l2_rt1320_l13); Arrow Lake was missing the
corresponding entry, so affected boards fell back to the generic
skl_hda_dsp_generic driver and only exposed HDMI outputs.
Confirmed on an MSI Raider 16 Max HX B2WI (MS-2651): the kernel now
correctly identifies the hardware and no longer falls back to the
generic HDA driver.
No dedicated topology has been built for this link0/link2 layout yet,
so sof_tplg_filename is set to a placeholder ("sof-arl-dummy.tplg")
rather than pointing at an existing but unrelated topology, per review
feedback.

Summary
Adds a SoundWire machine-driver match entry for Arrow Lake boards with an RT713 (SDCA "VB" jack/dmic variant) on link 0 and two RT1320 speaker amps sharing link 2 (unique_id 0/1, left/right).
Fixes #5934.
This codec pairing is already supported on Panther Lake (
ptl_sdw_rt713_vb_l2_rt1320_l13) and Lunar Lake (lnl_sdw_rt713_vb_l2_rt1320_l13); Arrow Lake was missing the corresponding entry, so affected boards fell back toskl_hda_dsp_genericand only exposed HDMI outputs.Hardware tested
MSI Raider 16 Max HX B2WI (MS-2651). Confirmed via kernel log that the machine driver now correctly identifies the hardware (requests the specified topology filename) instead of falling back to the generic HDA driver.
Topology filename
Per @bardliao's review on the linked issue,
sof_tplg_filenameis set to a placeholder (sof-arl-dummy.tplg) rather than pointing at the existing-but-unrelatedsof-arl-rt722-l0_rt1320-l2.tplg, since no topology has actually been built/validated for this specific link0/link2 layout yet.Note
I'm not in a position to build the actual topology myself (no access to SOF's topology2 toolchain setup), so this PR only covers the machine-driver detection side. Happy to test against a real topology if someone puts one together, or to answer any questions about the hardware.
