of: Use dts syntax when printing devicetrees ...

Our devicetree printing is close to correct dts syntax, so fix
some remaining differences:

- 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

ARM: mxs: make ssp gates parents of ssp dividers ...

When changing the rates of the ssp clocks we have to poll the
busy bit, but only when they are enabled. The current code can
not check this properly since the gates are registered as children
of the dividers. This has the effect that when the gate is disabled
the busy bit will be set forever resulting in a freezed system.

Fix this by making the gates parents of the dividers which allows
clk_is_enabled to return the correct result.

The Kernel has the same problem, but here the busy polling is
limited to 10ms, so probably noone noticed this.

The datasheet mentions that the ssp dividers shall only be changed
when the clocks are enabled. The kernel and barebox currently ignore
this. I don't know what effect violating this rule has.

OF: base: initalize from node in of_find_node_with_property ...

This adds initialization of from device node with root_node if NULL
is passed. This corresponds to the behavior of all other node iterators.

OF: base: fix iterator in of_get_next_available_child ...

of_get_next_available_child does not iterate but always tries the
same node over and over again. This first prepares the entry and
then uses list_for_each_entry_continue, instead of for_each_child_of_node
before.

OF: base: fix inifinite looping in node iterators ...

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.
