[PATCH 2/2] ALSA: hda/realtek: Fix headset mic on ASUS ROG Ally X

[Matthew Schwartz]

The ASUS ROG Ally X (RC72LA, PCI SSID 0x1043:0x1eb3) leaves the combo
jack microphone pin (0x19) unconfigured, so a headset microphone is
neither detected nor captured. Only the internal microphone is
available.

Add a pin override that configures node 0x19 as an external headset
mic, the same way the original ROG Ally does. The headphone output
fixup chain is preserved, so speaker and headphone routing are
unchanged.
