Joachim Eastwood b969afc8b7 ASoC: atmel-ssc: include linux/io.h for raw io 
Include linux/io.h for raw io operations in atmel-scc header.

This fixes the following build error:
  CC [M]  sound/soc/atmel/atmel_ssc_dai.o
sound/soc/atmel/atmel_ssc_dai.c: In function 'atmel_ssc_interrupt':
sound/soc/atmel/atmel_ssc_dai.c:171: error: implicit declaration of function '__raw_readl'
sound/soc/atmel/atmel_ssc_dai.c: In function 'atmel_ssc_shutdown':
sound/soc/atmel/atmel_ssc_dai.c:249: error: implicit declaration of function '__raw_writel'
