spi: Use void pointers for data in simple SPI I/O operations
Currently the simple SPI I/O operations all take pointers to u8 * buffers to operate on. This creates needless type compatibility issues and the underlying spi_transfer structure uses void pointers anyway so convert the API over to take void pointers too.
