[BUG] Topology sof-lnl-cs42l43-l0-2ch contains incorrect 4ch beamformer blob

[singalsu]

Describe the bug
The 2ch DMIC topology is built with embedded beamformer blob for 4ch system.

The target build is defined as:

"cavs-sdw;sof-lnl-cs42l43-l0-2ch;PLATFORM=lnl,NUM_SDW_AMP_LINKS=1,NUM_DMICS=2,
PDM1_MIC_A_ENABLE=0,PDM1_MIC_B_ENABLE=0,DMIC0_ID=3,DMIC1_ID=4,
PREPROCESS_PLUGINS=nhlt,NHLT_BIN=nhlt-sof-lnl-cs42l43-l0-2ch.bin,
SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,
SDW_JACK_OUT_STREAM=Playback-SimpleJack,SDW_JACK_IN_STREAM=Capture-SimpleJack,
HDMI1_ID=5,HDMI2_ID=6,HDMI3_ID=7,DMIC0_ENHANCED_CAPTURE=true,
EFX_DMIC0_TDFB_PARAMS=line4_pass,EFX_DMIC0_DRC_PARAMS=dmic_default"

The valid options for 2ch beamformer are "line2_generic_pm10deg" and "line2_pass".

To Reproduce
Build the topologies from git main or stable-v2.12 with scripts/build-tools.sh. Install the topology to PC
(I can't do this, I don't have such device)

Reproduction Rate
Always.

Expected behavior
EFX_DMIC0_TDFB_PARAMS=line2_generic_pm10deg or EFX_DMIC0_TDFB_PARAMS=line2_pass

Impact
Likely fail of capture, not sure what happens.

Environment

1. Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
   • Kernel: {SHA}
   • SOF: {SHA}
2. Name of the topology file
   • Topology: {FILE}
3. Name of the platform(s) on which the bug is observed.
   • Platform: {PLATFORM}

Screenshots or console output
If applicable, add a screenshot (drag-and-drop an image), or console logs
(cut-and-paste text and put a code fence (```) before and after, to help
explain the issue.

Please also include the relevant sections from the firmware log and kernel log in the report (and attach the full logs for complete reference). Kernel log is taken from dmesg and firmware log from sof-logger. See https://thesofproject.github.io/latest/developer_guides/debugability/logger/index.html

@singalsu fix merged, can you restest and close ?

[singalsu]

The fixes are in git main commit 7650d0a and in stable-v2.12 in commit b03f0e4 ("Tools: Topology2: Fix DMIC TDFB blob in sof-lnl-cs42l43-l0-2ch").
