So far every MMC driver is relying on a board specific init routine,
but as the Rockchip MMC driver is the first MMC device model user,
it requires a generic DM MMC init routine.
Add that to the MMC init path to enable the Rockchip driver.

Hi Simon,
this goes on top of your rockchip-working branch in the u-boot-dm
repo.
Not fully satisfied with this one, but the best I could come up with
without reading the whole of the device model code ;-)
This makes the SD card visible to U-Boot on my RK3288 dev board, I
can see partitions and load files from it. It gives me information
about the eMMC as well, but I haven't tested this so far except for
that mmc info.
Cheers,
Andre.
