Fabio Estevam 0865a75d41 ASoC: imx-ssi: Remove mono support 
Playing a mono track results in incorrect playback rate, ie, the audio
is played at a faster rate.

Remove mono support in the driver by setting 'channes_min' to dual-channel
and this allows mono tracks to be played correctly.

Shawn Guo a23dc69482 ASoC: imx: merge sound/soc/imx into sound/soc/fsl 
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.
