mmc: sdhci-esdhc-imx: extend card_detect and write_protect support for mx5
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.
