[PATCH 6/6] ASoC: fsl: check property 'compatible' for the machine name

[shawn.guo@linaro.org (Shawn Guo)]

The fsl_ssi probe function detects the client machine name using model
property of the device tree.  But it will not work for the ARM client
machines which are to be added.  The model property is given as a
descriptive string on all ARM device tree (arch/arm/boot/*.dts).
Instead, the compatible property gives the machine name.

It seems the fsl_ssi PowerPC users, machine mpc8610_hpcd and p1022ds,
basically have the same thing in model and compatible properties.
Detecting machine name using compatible property becomes a solution
working for both PowerPC and ARM users of fsl_ssi.
