The Lenovo Yoga 9 2-in-1 14IPH11 puts its CS42L43 codec and both CS35L57 amplifiers on SoundWire link 0. The existing cs42l43 targets describe machines that spread the same chips over links 2 and 3, so none of them matches; both amplifiers sit on the one link, hence NUM_SDW_AMP_LINKS=1. Add three targets so the kernel can pick one by DMIC count, as the existing cs42l43 and rt722 entries do: sof-ptl-cs42l43-l0 uses the SoundWire microphones behind the codec, the -2ch and -4ch variants the PCH DMICs. All three set EFX_SPK_IIR_PARAMS to highpass_30hz_0db_48khz instead of the cavs-sdw default of 100 Hz. The CS35L57 firmware applies excursion protection tuned for these woofers, so the generic high-pass only removes low end the amplifiers are built to reproduce. The matching kernel entry in soc-acpi-intel-ptl-match.c is sent separately. Tested on Fedora 44: the card comes up and woofers, tweeters, headphone jack and internal microphones all work.
