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.

- * The i.MX SSI core has some nasty limitations in AC97 mode. While most
- * sane processor vendors have a FIFO per AC97 slot, the i.MX has only
- * one FIFO which combines all valid receive slots. We cannot even select
- * which slots we want to receive. The WM9712 with which this driver
- * was developed with always sends GPIO status data in slot 12 which
- * we receive in our (PCM-) data stream. The only chance we have is to
- * manually skip this data in the FIQ handler. With sampling rates different
- * from 48000Hz not every frame has valid receive data, so the ratio
- * between pcm data and GPIO status data changes. Our FIQ handler is not
- * able to handle this, hence this driver only works with 48000Hz sampling
- * rate.
- * Reading and writing AC97 registers is another challenge. The core
- * provides us status bits when the read register is updated with *another*
- * value. When we read the same register two times (and the register still
- * contains the same value) these status bits are not set. We work
- * around this by not polling these bits but only wait a fixed delay.
