LF-601-1: ASoC: fsl_esai: Switch to imx-pcm-dma-v2
With the imx-pcm-dma, the dma channel will be allocated in probe,
with EDMA, the channel allocation is fixed for each peripheral.
In ASRC->ESAI->CODEC case, we have two sound card device, hw:x,0
and hw:x,1, with imx-pcm-dma, the channel for esai will be ocuppied
by hw:x,0 in boot up. when asrc platform driver want to request
the dma channnel for esai, it will fail.
So we switch to imx-pcm-dma-v2, with imx-pcm-dma-v2, the dma
channel is allocated when running, not in probe.
