The patch extends card_detect and write_protect support to get mx5 family and more scenarios supported. The changes include: * Turn platform_data from optional to mandatory * Add cd_types and wp_types into platform_data to cover more use cases * Remove the use of flag ESDHC_FLAG_GPIO_FOR_CD * Adjust some machine codes to adopt the platform_data changes * Work around the issue that software reset will get card detection circuit stop working With this patch, card_detect and write_protect gets supported on mx5 based platforms.
