alsa-ucm-conf-qcom-sdm670: upgrade to 1.2.9_git20241211
This causes Pipewire to appropriately control the VoiceMMode1 mixer and route call audio automatically.
The q6voice driver doesn't support enabling two ports at once. ConflictingDevice sections are added so the audio server doesn't try to turn on two paths at once.
HiFi profiles are prioritized over Voice Call profiles in Pipewire code, so the HiFi profiles are removed to force Pipewire to always select Voice Calls by default (e.g. when automatically switching to headphones). This cannot be done by callaudiod if it starts before pipewire-pulse and crashes.
