Fix Mic Mute LED no function on HP G12 laptops with ACP7.0 platform

[Chris Chiu]

[Impact]
HP G12 laptops on AMD platform with audio codec RTK ALC3315+CS35L56 amplifier, the MIC-Mute function is working but the LED state is not toggled accordingly.

[Fix]
The HP laptops on AMD platform needs a upstream patch e2cda4617656 ("ASoC: amd: acp: Refactor dmic-codec platform device creation") landed since 6.14-rc6 to correctly create a dmic-codec device instead of a audio card driven by snd_acp_legacy_mach.

[Test Case]
1. Boot and log into the HP G12 laptops powered by AMD.
2. Issue command `alsa-info` and check the generated output file
3. Make sure no card named snd_acp_legacy_mach listed in ALSA modules
4. press mic-mute hot-key and check if mic-mute is enabled or not by the OSD icon.
5. The mic-mute led should be ON when mic-mute enabled, OFF when disabled.

[Where problems could occur]
The patch identify the audio device for ACP7.0 correctly. Needs to verify on new AMD platforms which supports ACP7.0 devices.

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1023.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
