imx233: add support for sd/mmc probing

zenxfi2: add support for internal storage on the SD version

The code can now skip devices marked as PROBE if they fail to init, thus
making it possible to handle various kinds of internal storages. The current
code probably doesn't interplay nicely since it acquires pins and never
release them so it will probably break NAND code when it's ready but NAND code
is not ready yet anyway.
