This converts existing of_translate_address to recently added API. In
contrast to existing behavior, the new function honors ranges properties
properly. It now allows reg properties to be set as offset with respect
to the correspoding parent node.

According to ePAPR 1.1 spec, device tree nodes status can be either
"okay", "disabled", "fail", or "fail-sss". Barebox already has a function
to check for "disabled" nodes, while Linux checks for "okay" or "ok".
To synchronize Barebox and Linux OF APIs, rename of_node_disabled to
of_device_is_available and check for "okay" instead of "disabled" as it
also makes "fail"ed devices unavailable.

Barebox of_find_node_by_path requires a node to be passed as start node
to start searching. Linux OF API does not pass this node and no current
user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.

Barebox compares compatible, node names, and property names with strcmp.
Linux by default compares compatible and node names with strcasecmp. To
avoid inconsitencies between Barebox and Linux dts files, we convert to
these default string compare functions.

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.

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.
