[PATCH] of_property and phandles

[Sascha Hauer]

This adds the support for phandles to the of_property command.

The of_property command is able to manipulate devicetree properties,
but so far it hasn't been able to specify phandles. With this
series the following is possible:

of_property -s /soc/somenode propname </soc/someothernode 0xdeadbeef>

The /soc/someothernode is inserted into the property as phandle.

The projected usecase currently is to chose a display out of several
possible during runtime.
