This large patch removes all trailing whitespace from dtc (including
libfdt, the testsuite and documentation). It also removes a handful
of redundant blank lines (at the end of functions, or when there are
two blank lines together for no particular reason).
As well as anything else, this means that quilt won't whinge when I go
to convert the whole of libfdt into a patch to apply to the kernel.

It is not an error for /chosen (or any of its children) to be missing.
It is not a requirement that the output of dtc be a complete, valid
device tree, as it may be intended that the dtb be passed through boot
code that will complete it. Thus, do not complain.

Remove warning for missing interrupt-controller property
under /chosen. There is consensus that this
property does not belong here.
Also, add a warning if interrupt-controller _is_ found
under /chosen.

dtc allows nodes to have labels, which at present are just re-emitted
as symbols at the appropriate places when using asm-mode output. It
also allows "references" where the notation &/path/to/node in a cell
list will be replaced with the phandle of the referenced node.
This patch extends the reference syntax to allow references to labels
instead of just full device paths. This allows nodes deep within the
tree to be referenced with a shorter more convenient name. References
to labels are distinguished from reference to paths by the fact that
paths must start with a /, but labels can never start with a /.

At present, the tree checking code in dtc will die with an assertion
failure if given a tree which has the invalid value 0 or -1 in a
property which should contain a phandle. This patch fixes the check
to die more gracefully with an error message indicating the invalid
phandle value.

The linux,platform property in /chosen was obsolete almost as soon as
it was invented. Remove the check for it from dtc, which just tends
to lead to irritating spurious failures.

dtc always sets the physical boot CPU to 0xfeedbeef. Add a -b option to
set this. Also add warnings when using the wrong property with the
wrong blob version.
