Recently the node names in i.MX6 device tree files have changed. The
leading zeroes were removed from the addresses. With this a newer
barebox doesn't find the nodes to fixup in an old device tree and
an older barebox doesn't find the nodes in a new device tree. To
fix this we create new names of the nodes based on things that hopefully
don't change: We iterate up to a node which is MMIO space mappable
and get a name that starts with "[adr]". For the remaining parts of
a node we add "<reg>" when the hierarchy level has a "reg" property
and only as last fallback we add "{nodename}" in curly brackets.
This name is safe against node name changes and also against adding
a new hierarchy level in the device tree (when for example a bus level
is added).
This series aims for v2018.01.1
