mvsdio_platform_data allows to pass card detect and write protect gpio numbers to the driver. Some kirkwood boards don't use both pins as they are not connected, and don't set the corresponding value in platform_data. This will leave the unset values in platform_data initialized as 0, which is in fact a valid gpio pin. mvsdio will grab that pin and configure it as gpio, which in turn breaks nand controller as mpp0 also carries nand_io2. This patch fixes the above by initializing unused gpio functions in the platform_data with an invalid (-1) value.
