MLK-11179 ASoC: fsl: implement specify audio DMA buffer size from devicetree
If the property "fsl,dma-buffer-size" is present, using the specified buffer size. Otherwise, using the default audio buffer size. Signed-off-by: Zidan Wang <zidan.wang@freescale.com> (cherry picked from commit bba153dd92a4f58b81c4c26fb3a95c45445c65e0)
