[SeongJae Park]

Fix the pointer-integer size mismatch warning below:
        drivers/spi/spi-gpio.c: In function ‘spi_gpio_setup’:
        drivers/spi/spi-gpio.c:252:8: warning: cast from pointer to integer of
                        different size [-Wpointer-to-int-cast]
           cs = (unsigned int) spi->controller_data;
                ^
