This patch adds in support for the DS570 IP. It's register compatible with the DS464, but adds support for 8/16/32 SPI. The 8/16/32 support is added by attaching callbacks reading/writing the proper amount of data. To indicate to the driver which amount of bits to use a new field is introduced in the platform data struct.
