dm: mmc: Add a way to bind MMC devices with driver model
Binding an MMC device when CONFIG_BLK is enabled requires that a block device be bound as a child of the MMC device. Add a function to do this. The mmc_create() method will be used only when DM_BLK is disabled. Add an unbind method also. Signed-off-by: Simon Glass <sjg@chromium.org>
