msm: audio: qdsp6v2: Fix noise in Tunnel mode Mp3/AAC audio playback

Modify the async_write API to send Encode bitstream buffer address
for non-tunnel mode with skipping meta data. And for tunnel mode
buffer address remains same as there is no meta data for
Tunnel mode and is sent to DSP without any change in this value.

ASOC: Fix mutex unlock issues for error cases

Unlock mutex acquired within the same function during
error case handling, which was not unlocked before.
This could affect system stability if there are issues

msm: audio: qdsp6v2: PCM Encoder is configured to native channel count

Impact:
When the content switches from 5.1 channels to mono. Noise is heard
in one of the channels.

Problem:
At the start of the playback, number of output channels of PCM
Encoder is configured to 2 when the number of channels in the input
stream are greater than 2. This is done to confine maximum output
channels from PCM encoder to 2.

Change:
Modify output channel configuration of PCM encoder to native
channel count as Q6 decoder takes care for converting channel count
to 2 for the clips with channel count greater than 2.

msm: audio: qdsp6v2: Set end of frame flag to avoid aac multiseek issue

- During aac playback, multiple seek lead to target freeze.
- DSP starts decoding when internal buffer size maximum is
  reached, hence, if there are corrupted frames in that buffer,
  the entire set will not be decoded. This results in target freeze.
- Fix is to set the end of frame flag in the buffers that
  are sent to DSP for decoding.

msm: audio: qdsp6v2: remove unmap ion region before disable

In the use case of audio playback in non tunnel mode, in audio release
unmap is called twice, before and after audio disable. This is
resulting to request DSP to unmap the region twice. Remove the unmap of
the ion region before audio disable.

msm: audio: qdsp6v2: Fix seek issue in tunnel player

- Seeking to 0 position during tunnel playback, music stream
  jumps to incorrect postion.
- Initial buffer after seek to new position is corrupted as
  flush ioctl is not synchronous. Ioctl FLUSH is posting
  CMD_FLUSH to DSP, but WRITE_DONE to user space are posted
  even before it receives FLUSH ack from DSP.
- Fix is to wait for FLUSH ack from DSP, then post the
  WRITE_DONE events to user space, which will ensure FLUSH
  is completely handled.
