[ Upstream commit a1f31cc4e98e1833f53fd2c6e9a218d6b86f5388 ]
The newly added driver requires DMA support and fails to build
when that is disabled:
aarch64-linux-ld: sound/soc/fsl/fsl_aud2htx.o: in function `fsl_aud2htx_probe':
fsl_aud2htx.c:(.text+0x3e0): undefined reference to `imx_pcm_dma_init'
Fixes: 8a24c834c053 ("ASoC: fsl_aud2htx: Add aud2htx module driver")
