ALSA: hda/realtek: Rename Line Out control to Headphone on ThinkPad X1 Carbon 6th
The ThinkPad X1 Carbon 6th Gen (ALC285, SSID 17aa:225c) has no physical
Line Out jack. The 3.5mm headphone jack is wired to the headphone DAC,
but the ALSA HDA driver names the corresponding control as
"Line Out Playback Volume" (node 0x02).
PipeWire's ALSA Card Profile (ACP) silences "Line Out" when headphones
are activated, which incorrectly mutes the headphone output.
Add a quirk to rename the control to "Headphone Playback Volume" via
alc285_lenovo_dac_rename().
Tested on openSUSE Tumbleweed (kernel 7.1.5):
- Control renamed successfully, no name collision with "Headphone Playback Switch"
- Headphone output works across multiple PipeWire/WirePlumber restarts
and port switches
