    Summary: an OF-specific wrapper around the mmc_spi platform code.

    I think a wrapper to encapsulate all the OF-specific knowledge makes
    much sense here.

    The only thing that looks odd to me about this is that the wrapper
    is a spi_device rather than an of_device. To me it makes more sense
    to just have an of_device setting up the right spi_device. (Though
    maybe I missed some discussion about why that can't work.)

    Example: drivers/usb/host/sl811_cs.c does that for PCMCIA card
    that just wraps an sl811 chip that's more often used standalone.
    The PCMCIA descriptors being analagous to OF device table entries.
