[PATCH] ASoC: fsl: select SND_SOC_IMX_PCM_DMA where needed

[arnd@arndb.de (Arnd Bergmann)]

Since commit 204dec93eaa "ASoC: fsl: Allow to select individual common
options", it is possible to enable SND_SOC_FSL_SSI and SND_SOC_FSL_SPDIF
manually. However, these two options are for drivers that both
require the imx-pcm-dma framework and result in a link error if that
is not provided.

This changes Kconfig to automatically select SND_SOC_IMX_PCM_DMA
to avoid the problem, as we do for other drivers that need the same
framework.
