xilinx_spi: add support for the DS570 IP.
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.
