alsa: ucm - use possible mixer private device prefix for ELD controls

Browse source 
If UCM defines the private alsa-lib configuration, the ELD controls
are expected to use this device configuration too.

With this change:

  I: [pulseaudio] alsa-util.c: Successfully attached to mixer '_ucm0009.hw:Loopback'

Without:

  I: [pulseaudio] alsa-util.c: Successfully attached to mixer '_ucm0009.hw:Loopback'
  I: [pulseaudio] alsa-util.c: Successfully attached to mixer 'hw:4'
