Add platform device id to check whether the SSC controller support
pdc or dam for data transfer
If match "at91rm9200_ssc", which support pdc for data transfer
If match "at91sam9g45_ssc", which support dma for data transfer

Include linux/io.h for raw io operations in atmel-scc header.
This fixes the following build error:

The Synchronous Serial Controller (SSC) on Atmel microprocessors are
capable of tranceiving many frame based protocols, like I2S. Tested on the
AT32AP7000/ATSTK1000.
This driver is used in the ALSA sound driver for the AT73C213 external DAC
on the ATSTK1000 development board for AVR32. This sound driver will be
submitted soon.
Hardware documentation can be found in the AT32AP7000 data sheet, which can
be downloaded from
