Freescale PowerPC and ARM/IMX families share the same SSI IP block. The patch merges sound/soc/imx into sound/soc/fsl, so that the possible code sharing and consolidation can happen. This is a plain merge, except that menuconfig SND_POWERPC_SOC is added in Kconfig for PowerPC platform as a correspondence to SND_IMX_SOC for IMX platform.
