supports-{emmc, sd, sdio} aren't vaild properties.
If you do want to speedup the init process and you
could add no-sd and no-sdio for emmc.
num-slots is deprecated and would be cleaned from all dts for 4.14
cycle. And disable-wp is only used for SD card now.
The same comment for the following sd and sdio nodes.
