qaqland d1c372f5ee alsa-udev: support alsa.ignore-dB 
Some sound cards are only adapted for Android/macOS and other
systems, without considering Linux. The hardware-reported dB
volume is incorrect (while the percentage volume is normal).
Add support for the ignore-dB option to simplify compatibility.

For example, the 3206:0798 HP SIMGOT GEW1 Sound Card reports:

numid=4,iface=MIXER,name='PCM Playback Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=100,step=0
  : values=100,100
  | dBminmax-min=0.00dB,max=0.39dB

This dB value does not match actual audio perception, and the
vendor attributed this issue to non-target system compatibility.
