mm-audio: Fix delay at the start of MT voice call

- Reducing the delay for playing the RINGTONE
  before voice call is accepted saves,appr 340ms.
- on this platform reducing the delay wont affect
  the RINGTONE as the delay in setting up voice
  path after accepting the voice call will
  compensate RINGTONE buffers with kernel and
  firmware played on the device.
