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.

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.

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.

| mtd core: call driver write function with complete buffer
|
| mtd->write is supposed to loop around pages internally, no need
| to do this in mtd_write. This fixes a huge write performance drop
| with the m25p80 driver when it was converted to a mtd driver recently.
| Since mtd->writesize is 1 for this driver mtd_write ended up doing
| single byte writes on the flash.
Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.
