ASoC: fsl: add memory to memory function for ASRC
Merge series from Shengjiu Wang <shengjiu.wang@nxp.com>: This function is base on the accelerator implementation for compress API: 04177158cf98 ("ALSA: compress_offload: introduce accel operation mode") Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the patch 1 and patch 2 is for refining the code to make it can be shared by the "memory->asrc->memory" driver. Other change is to add memory to memory support for two kinds of i.MX ASRC modules.
