ASoC: msm8x10: add support to split SD0/1 as two seperate BE.

SD0 and SD1 are driven by single DMA channel. this makes it
impossible for any audio session to be sent to SD1 output
without mixing with SD0 data contents.

Allow user to route audio to a new AFE PORT introduced to
send data to SD1 without mixing with SD0 contents. The user
however needs to group the ports before opening any of the
AFE ports.

ASoC: dapm: fix race condition in dapm

Dirty widget list can be accessed by multiple paths

Since dapm_set_pin and dapm_force_enable_pin function
accesses the dirty list, protect it using the dapm mutex.

msm: Create shadow files under /sys/kernel/ipv4

The TCP delayed ack parameters can be configured from user space
application which runs with non-root credentials and does not have
direct write access to /proc entries. This commit creates shadow

ASoC: msm: qdsp6v2: Update pcm media format block to use correct stream id

Repeat mode is not working in pcm offload path. When two streams
are used in a single session pcm format block should be sent
specific to each stream. Data sent on stream 2 is ignored by DSP
because pcm format block is always sent on stream 1. Fix is to
update pcm media format block to use correct stream id before
data is sent to DSP.

ASoC: compress: fix the target not going to TCXO shutdown

The error code propagated from the flush cmd in the trigger stop
is causing the error in the state of the soc compress framework.
This hinders in closing the BE connected to the FE.
If the AFE is not closed it prevents the target to go into TCXO
shutdown.
Fixed by removing the error handling of the flush command in the
trigger stop, since failure in flush doesn't signify the
failure in the stop command.
