This patch adds description for no-sd, no-sdio, no-mmc. We expose
these to DT as some of the controllers are unable to deal with
special cmd type due to hw limitation.

Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com>

Changes in v2:
- amend the description of these properties and the commit msg
