Convert users of PRINTF_CONVERSION_RESOURCE to %pa ...

printf now supports printing resource_size_t directly, convert
all users of the previously used PRINTF_CONVERSION_RESOURCE over
to %pa.

of_path: Drop possible further extensions of device-path property ...

Originally it was intended to further extend the multi string property
device-path further with more elements, like for example a filename. It
turned out though that this is too complex and instead of further
extending the property we should instead create additional properties,
so this mechanism is removed with this patch to make the code simpler.

environment: Support env from file in a file-system via device tree ...

Current barebox,environment node only allows specifying a raw device or
partition to load an environment from.  Some boards, like OMAP and
SoCFPGA, instead want to use a file located in a FAT filesystem.
Extend the device tree bindings with a new property 'file-path' that
will trigger this behavior.

This allows any board using this driver to get the env from a file or
from a raw device, instead of each machine type being either raw
device only or file only.

of_path: Fix bug with partitions, simply code ...

In commit 75b6827 using a path that
has a partition description broke.

Fix this and simpfy the code some.

There is no need to loop over each string in the path property:  it's
defined to have at most one parition description, no extant dts has
more than one, and how it would handle more than one didn't make sense
anyway.

Once not looping, __of_find_path() just needs the partition
description text, not both the original node and property name to look
it up from.

When using a partition description, don't lookup the cdev of the node
just to replace it with the partition's cdev.

This patch adds the function of_find_path_by_node(), which is similar to
of_find_path(), but it translates a device tree node into a barebox device path

cdev: Add function to find cdev by device_node ...

This adds a device_node member to struct cdev and a function
to find a cdev by device_node.
This also removes the setting of cdev->dev->device_node in
the of partition parser. We must not set the device since it
may not refer to a partition but to a whole device with partitions.

of_alias_get assumed that a DT path is always the full node path,
whic is not necessarily the case, as there are other valid path
descriptions. All of them are handled by of_find_node_by_path.

As there is already a preparsed list with all DT aliases that handles
this case properly we can simply reuse that one.
