ARM: legoev3: convert to driver model
This converts LEGO MINDSTORMS EV3 to the driver model. MMC, SERIAL, SPI
and SPI_FLASH are converted.
The device tree contains only the minimal nodes required by U-Boot
since the size of U-Boot is limited to 256K on this device.

If you are booting from the microSD card, it is enough to just write uboot.bin
to the flash. If you are not using a microSD card, you will need to create an
image file using the layout described above.

+IMPORTANT: The EEPROM bootloader only copies 256k, so u-boot.img must not
+exceed that size!
