ASoC: fsl_rpmsg: initialise pointers to NULL

This fixes the following sparse warnings:

sound/soc/fsl/fsl_rpmsg.c:45:45: sparse: sparse: Using plain integer as NULL pointer
sound/soc/fsl/fsl_rpmsg.c:45:56: sparse: sparse: Using plain integer as NULL pointer

Fixes: b73d9e6225e8 ("ASoC: fsl_rpmsg: Add CPU DAI driver for audio base on rpmsg")
