ASoC: fsl_asrc_m2m: select CONFIG_DMA_SHARED_BUFFER

Randconfig builds without dmabuf result in this link error from
the fasl-asrc driver:

ERROR: modpost: "dma_buf_put" [sound/core/snd-compress.ko] undefined!
ERROR: modpost: "dma_buf_export" [sound/soc/fsl/snd-soc-fsl-asrc.ko] undefined!

Add the missing 'select' statement.
