After removing of_platform_default_populate() calls the atmel-ebi driver
was affected by deferred probing.  platform_driver_probe() is
incompatible with deferred probing.  This led to atmel-ebi driver
eventually not being probed on at91 sam9x60-curiosity and other sam9x60
based boards.  Subsequently the nand-controller driver (nand-controller
being a child node of ebi) on that platform was not probed and thus raw
NAND flash was inaccessible, preventing devices to boot with rootfs on
raw NAND flash (e.g. with UBI/UBIFS).
