ASoC: fsl_aud2htx: select SND_SOC_IMX_PCM_DMA 

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: 8a24c834c0 ("ASoC: fsl_aud2htx: Add aud2htx module driver")
