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.
