When kernel is booted using DT, there is no guarantee that Davinci
NAND device has been created already at the time when driver init
function is executed. Therefore, platform_driver_probe() can't be used
because this may result the Davinci NAND driver will never be probed.
The driver probing has to be made with core mechanism.
