[PATCH] of: partition: Also add partitions created by addpart to the boot dtb

[Uwe Kleine-König]

A partition added interactively using addpart was added in
of_partition_fixup() before commit aec676b568 ("cdev: record whether
partition is parsed from OF").

Restore that behaviour. To do that a new flag DEVFS_PARTITION_FOR_FIXUP
is created that behaves very similar what DEVFS_PARTITION_FROM_OF did
before. The only difference is that addpart makes use of it (and that
stat uses a different string to describe it).
