[PATCH v1 00/20] dts: avoid DT breakage new fancy DTC v1.7.0 syntax

[Ahmad Fatoum]

The fresh v1.7.0 release of the device tree compiler now contains
fancy new syntax:

  &{i2c1/at24 at 50} {
	partitions {
		/* something */
	};
  };

instead of &{/soc/bus1/bus2/i2c at 12345678/at24 at 50}, which is overly
verbose or &i2c1 { at24 at 50 }, which will break once someone renames
it upstream to please the schema checker.

Let's update to this new DTC release and change a lot of non-portable DT
we have to use this new syntax or use existing labels if available or
just absolute paths. This also fixes some breakage, but most of it is
future-proofing.

I did some build testing and fixed the fallout, but Sascha's build of all
configs may turn up some breakage too, which I would fix for v2.
