Subject: [PATCH] ALSA: hda/realtek: Fix headset mic on ASUS Zenbook 14

Add a PCI quirk to enable microphone input on the headphone jack on
the ASUS Zenbook 14 UM3406HA laptop.

This model uses an ALC294 codec with CS35L41 amplifiers over I2C,
and the existing fixup for it did not enable the headset microphone.
A new fix is introduced to get the mic working while keeping the
amplifier settings correct.

Fixes: 61cbc08fdb04 ("ALSA: hda/realtek: Add quirks for ASUS 2024 Zenbooks")
