If the master device has callbacks for _get/put_device()
and this MTD has slaves a get_mtd_device() call on paritions
will never issue the registered callbacks.
Fix this by propagating _get/put_device() down.

Instead of creating our files in /nandsim/,
create one directory per instance.

A first step to support multiple nandsim instances...
Remove global variables and put them into struct nandsim.

Do it like UBI and support in future up to 32 instances.
For now we still keep a single instance and allow more when
all global state has been removed.

del_mtd_device() is allowed to fail.
i.e. when the MTD is busy.
Unregister the reboot notifier only when we're really
about to delete the MTD.

If the master device has callbacks for _get/put_device()
and this MTD has slaves a get_mtd_device() call on paritions
will never issue the registered callbacks.
Fix this by propagating _get/put_device() down.
