of: Also print disabled nodes ...

It's confusing to set the status of a node to disabled and afterwards
it's invisible. Similarly it's confusing to be able to enable invisible
nodes.

Also print disabled nodes.

of: populate devices based on "simple-bus" property ...

We used to populate the devices from the devicetree based on the
presence of the 'reg' property. This is incorrect since this only
allows us to probe devices with resources.
Instead use the 'simple-bus' property to see if we have iterate
deeper. This also registers devices with their buses as parents.

of: Call of_add_memory from of_probe ...

memory is always in /mem, so call of_add_memory from of_probe once
instead of in the recursive tree iteration. This makes it possible
to limit the device population to nodes with the "simple-bus" property
set.

of: When checking for existing devices also check resource end ...

When registering devices from the devicetree we check if these
devices already exist. When doing this not only check the resource
start but also the resource end.
This helps with the probing of simple buses for which child nodes
often begin at the very same address as the parents.

of: separate out "generic" memory bank adding ...

This patch separates out the "generic" memory
segment registration function (of_add_memory_bank())
from of_add_memory().
The MIPS architecture has different view on memory
resources than the ARM and PPC architectures
so the "generic" of_add_memory_bank() is
unusable for the MIPS architecture.
We can add MIPS-specific of_add_memory_bank()
into arch/mips code.

of: fix how an initrd is passed to Linux ...

Linux expects linux,initrd-end to contain the first unused address. As
this doesn't match the end semantic used by barebox (i.e. end contains
the last used address) adding one is necessary.

Without this change Linux fails for me to correctly extract a gzipped
cpio archive provided as initrd.

of: parse phandles before probing devices ...

The phandles have to be parsed completely before registering the devices

in their probe.

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.
