[Impact]
On various ASUS Vivobook with Realtek audio codec ALC256, the audio input device will disappear thus the microphone does not work anymore. It happens after this commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort") on 6.14-rc1.

[Fix]
Backported patches for ASUS Vivobook which use the correct fixup which is not affected by the order problem caused by commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort")

[Test Case]
1. Get ASUS Vivobook laptops and boot up.
2. Check if the audio input device exist
3. use `arecord` to record sound with the microphone

[Where problems could occur]
They are only quirked for ASUS Vivobook SSIDs with ALC256. Should have no impact for other platforms. The risk should be low.
