ASoC: compr: Disable soft-pause for compress playback

Soft-pause (i.e pause ack after a timeout) adversely affects
audio/video sync during pause/resume use cases leading to some
frame drops. Disable this feature for compress playback.

ASoC: msm: Configure correct gain on set Volume command

Output channel gain is product of per channel gain and master gain.
Hence if only per channel gain is set and master gain is set to 0
then no audio is heard at the output.
Ensure that if we change per channel gain then we set master gain
to unity and vice versa. This enables only one gain to be effective.

ASoC: msm: set the master gain to 0 on DSP while configuring

- Mute media volume and play any music clip then reboot
  the phone. Play music again noise comes. This noise
  is introduced in DSP/LPASS.

- DSP suggestion is to mute master volume gain while
  configuring ASM session to avoid such noise at
  begining of asm playback.
