mmc_spi: Add support for OpenFirmware bindings
The support is implemented via platform data accessors, new module (of_mmc_spi) will be created automatically when the driver compiles on OpenFirmware platforms. Link-time dependency will load the module automatically. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
