A pointer to plat_nand_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

This patch sets mtd->name to the platform bus ID in the plat_nand
driver, so that you can specify partitions readily with mtdparts=.

Currently it relies on nand_base filling in the name from the device,
which results in names like "NAND 256MiB 3,3V 8-bit", that you can't
use with cmdlineparts.

Since 43cc71ee, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable MTD NAND
platform drivers, to re-enable auto loading.

NOTE: at91_nand for some reason disallows modular builds.  I'm assuming that's
just an oversight that will be fixed.
