For some reason, the SSM2518 codec driver has device tree bindings 
specified (Documentation/devicetree/bindings/sound/ssm2518.txt) but the 
actual driver doesn't seem to support DT. This patch adds rudimentary 
support for the compatible property so that the driver can be used in a DT 
based setup.
