[PATCH] ASoC: fsl_asrc_dma: fully initialize structs

The driver uses two statically ininitialized struct dma_slave_config,
but only one of them is initialized to zero. Initialize config_be to
zero as well to make sure that no fields are filled with random values.
Let the compiler do this instead of explicitly calling memset() which
makes it easier to read.
