Git is gaining support to display the closest node to the diff in the
hunk header via the 'dts' diff driver.  Use that driver for all dts and
dtsi files so we can gain some more context on where the diff is.
Taking a recent commit in the kernel dts files you can see the
difference.

With this patch and an updated git

Git can be told to apply language-specific rules when generating diffs.
Enable this for C source code files (*.c and *.h) so that function names
are printed right.  Specifically, doing so prevents "git diff" from
mistakenly considering unindented goto labels as function names.
