ata: add ata logical device to defer probe ...

ata device usually take a long time to spin up, so it makes sense
to only spend this time when the device is actually used.

This adds a logical ata device and attaches a 'probe' parameter
to it, similar to what MMC does.

fix another brown paper bag bug introduced with compile time loglevel ...

__pr_printk is a define which uses a local variable 'ret'. This
means that whenever someone does a pr_*("ret: %d\n", ret);
ret will be 0.

Fix this by writing this without a local variable.

bootm: Pass unflattened devicetree to handlers ...

This makes it possible to modify the tree in the handlers.
This is necessary because the initrd addresses are only
known inside the handlers, but not to the generic bootm
code.

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.
