nand_init() does not only create the NAND device, it also realizes
the device with qdev_init_nofail() already. So we must not call
nand_init() from an instance_init function like sl_nand_init(),
otherwise we get superfluous NAND devices in the QOM tree after
introspecting the 'sl-nand' device. So move the nand_init() to the
realize function of 'sl-nand' instead.
