David Gibson f240527e54 Fix bug with references to root node 
At present, the lexer token for references to a path doesn't permit a
reference to the root node &{/}.  Fixing the lexer exposes another bug
handling this case.

This patch fixes both bugs and adds testcases.

Grant Likely 83da1b2a4e Allow device tree to be modified by additonal device tree sections 
This patch allows the following construct:

/ {
	property-a = "old";
	property-b = "does not change";
};

/ {
	property-a = "changed";
	property-c = "new";
	node-a {
	};
};

Where the later device tree overrides the properties found in the
earlier tree.  This is useful for laying down a template device tree
in an include file and modifying it for a specific board without having
to clone the entire tree.
