of_property command: Fix crash with empty property value ...

the of_property command crashes when an empty property value
was given. This is because xrealloc is called with a length
argument of 0. Fix this.

bootm: Use of_print_nodes instead of fdt_print ...

Now that we use the unflattened tree in bootm we can use of_print_nodes
instead of printing the flattened tree.

of: Pass barebox internal format devicetree to of_get_fixed_tree ...

With this every devicetree is first converted to the barebox internal
format before it's converted back to dtb again.

oftree command: retire CMD_OFTREE_PROBE Kconfig option ...

Whether or not the user wishes devicetree probe support can
now be decided indepentently of the oftree command, so retire
the CMD_OFTREE_PROBE option and use OFDEVICE in the code instead.

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.

Add pread and pwrite functions.

Split read and write functions to save some space.
The functions pread and pwrite saves and sets the file
position to a given offset and restore them afterwards.

This also makes the nandtest command use these function
which is necessary to not break compilation for the nandtest
command.

libmtd: rename functions from mtd_* to libmtd_* ...

The kernel nowadays has mtd_read/write and other functions. In
barebox we also have these functions, but with a different prototype,
namely they correspond to the libmtd userspace functions. Rename
these functions to libmtd_* to avoid name clashes with future mtd
updates.
