David Gibson bad5b28049 Fix assorted sparse warnings
This fixes a great many sparse warnings on the fdt and libfdt sources.
These are mostly due to incorrect mixing of endian annotated and native
integer types.

This includes fixing a couple of quasi-bugs where we had endian conversions
the wrong way around (this will have the right effect in practice, but is
certainly conceptually incorrect).

This doesn't make the whole tree sparse clean: there are many warnings in
bison and lex generated code, and there are a handful of other remaining
warnings that are (for now) more trouble than they're worth to fix (and
are not genuine bugs).

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.

Kim Phillips 38ad79d339 dtc/tests: don't include fdt.h prior to libfdt.h
tests will need fdt type definitions provided in a subsequent patch
to libfdt_env.h.  Since libfdt.h includes libfdt_env.h in the right
order anyway, just remove the fdt.h include.

David Gibson 9878f30f31 dtc: Handle linux,phandle properties which self-reference
Currently, dtc will generate phandles for nodes which are referenced
elsewhere in the tree.  phandles can also be explicitly assigned by
defining the linux,phandle property.  However, there is no way,
currently to tell dtc to generate a phandle for a node if it is not
referenced elsewhere.  This is inconvenient when it's expected that
later processing on the flat tree might add nodes which _will_
the node in question.

One way one might attempt to do this is with the construct:
	mynode: mynode {
		linux,phandle = <&mynode>;
		/* ... */
	};
Though it's a trifle odd, there's really only one sensible meaning
which can be assigned to this construct: allocate a unique phandle to
"mynode" and put that in its linux,phandle property (as always).

Currently, however, dtc will choke on this self-reference.  This patch
corrects this, making the construct above give the expected results.
It also ensures a more meaningful error message is given if you
attempt to process the nonsensical construct:
	mynode: mynode {
		linux,phandle = <&someothernode>;
		/* ... */
	};

The 'references' testcase is extended to cover this case, as well.

David Gibson 01a2d8a3e9 dtc: Make many functions 'static'
This patch marks various functions not shared between c files
'static', as they should be.  There are a couple of functions in dtc,
and many in the testsuite.

This is *almost* enough to enable the -Wmissing-prototypes warning.
It's not quite enough, because there's a mess of junk in the flex
generated code which triggers that warning which I'm not yet sure how
to deal with.

David Gibson 6aaee513dd dtc: Fix some printf() format warnings when compiling 64-bit
Currently, dtc generates a few gcc build warnings if built for a
64-bit target, due to the altered type of uint64_t and size_t.  This
patch fixes the warnings (without generating new warnings for 32-bit).
