xilinx_spi: Switch to iomem functions and support little endian.
This patch changes the out_(be)(8|16|32) and in_(be)(8|16|32) calls to 32 bits ioread/iowrite.
The read and write function are attached to the internal struct as callbacks, callback
is selected depending on endianess.
This will also build on platforms not supporting the in/out calls for instance x86.
