MLK-11398: ASoC: fsl_asrc: Add Memory to Memory support

cherry-pick below patch from v3.14.y:
ENGR00330403-4: ASoC: fsl_asrc: Add Memory to Memory support

ASRC M2M function is not able to put upstream due to its self-designed
ioctl protocol. So I just make a single patch for it and make it merge
into P2P driver as simply as possible.

The patch can only be maintained internally unless some one designs a
new protocol or implement the originally protocol by using some common
approach provided by Linux Kernel.
