It is currently possible to have CONFIG_SND_ATMEL_SOC_SSC=y with either CONFIG_SND_ATMEL_SOC_PDC=m or CONFIG_SND_ATMEL_SOC_DMA=m. This results in a driver that compiles but does not link with this kind of error:

sound/built-in.o: In function `atmel_ssc_set_audio': (.text+0x87d90): undefined reference to `atmel_pcm_pdc_platform_register' sound/built-in.o: In function `atmel_ssc_put_audio': (.text+0x8879a): undefined reference to `atmel_pcm_pdc_platform_unregister'

Introduce new config options SND_ATMEL_SOC_SSC_PDC and SND_ATMEL_SOC_SSC_DMA which should be used by the board drivers and the correct logic to properly select the SND_ATMEL_SOC_PDC and SND_ATMEL_SOC_DMA states.
