Julius Werner 6702b68a79 device_tree: Add phandle caching and lookups 
This patch caches phandles when unflattening the device tree, so we
don't have to look up the phandle property again every time we're trying
to find the phandle of a node. This is especially important when
supporting phandle lookups, which are also added. In addition we keep
track of the highest phandle in the whole tree, which will be important
for applying overlays later.

With this, dt_get_phandle(node) becomes obsolete because the phandle is
already available as a member variable in the node.

This patch was adapted from depthcharge's http://crosreview.com/1536385
