of: partitions: pass struct cdev as argument ...

pass a struct cdev instead of the cdev name to of_parse_partitions.
This is available to the caller anyway and makes it easier to use
additional stuff from the cdev (like knowing whether it's a mtd
device).

of: make OFDEVICE a user selectable option ...

OFDEVICE decides whether or not we compile in support for probing
devices from the devicetree. Let the user decide this explicitly.
This makes the oftree, of_node and of_property commands independent
of devicetree device support since being able to manipulate
devicetrees has nothing to do with probing devices from the devicetree.

of: let of_unflatten_dtb return the unflattened tree ...

In order to be able to handle multiple devicetrees, do not assume
the tree to be unflattened is the barebox internal one. Instead,
just return a pointer to it and assign the barebox internal root_node
external to the unflatten function.

of: remove allnodes list ...

The allnodes list makes it hard to handle multiple devicetrees. Having
a list to iterate over all nodes of a tree is still good to have though.
This patch uses the list_head of the root node as the head of the list.
This way the root node is no longer part of the list, but when iterating
over a tree the root node is not interesting anyway.
