This breaks the build for me:

ld: sound/soc/atmel/atmel_ssc_dai.o: in function `atmel_ssc_set_audio':
atmel_ssc_dai.c:(.text+0xbd9): undefined reference to `ssc_request'
ld: sound/soc/atmel/atmel_ssc_dai.o: in function `atmel_ssc_put_audio':
atmel_ssc_dai.c:(.text+0xc74): undefined reference to `ssc_free'

It's not selecting the SSC comon code.  It also looks like it'd be
sensible to add a dependency on the platform (or at least architecture),
with a || COMPILE_TEST to help with build coverage.
