David Gibson 63dc9c7113 dtc: Whitespace cleanup
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.
