where parts are loaded at runtime. Here we don't want to keep the list of

Our devicetree printing is close to correct dts syntax, so fix

- Use an equal sign instead of a colon to separate a poperty name and
a value
- Add a semicolon at the end of properties
- Make sure we do not print a separator for empty properties

of_find_node_by_name suffers from infinite looping, because it
does not check for root node of the tree iterated over. This
fixes this by checking for node->parent to determine whether
the last node has been reached.
Since of_tree_for_each_node does not iterate over the whole tree,
but only over the remaining nodes, rename it to
of_tree_for_each_node_from.

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.

passes the current root_node. Also, all current users of that function
