The Linux kernel receives many patches to the devicetree files each
release. The hunk header for those patches typically show nothing,
making it difficult to figure out what node is being modified without
applying the patch or opening the file and seeking to the context. Let's
add a builtin 'dts' pattern to git so that users can get better diff
output on dts files when they use the diff=dts driver.
The regex has been constructed based on the spec at devicetree.org[1]
and with some help from Johannes Sixt.

Changes from v2:
* Added a few more tests for comments after and before {
* Added a root node test
* Support for root node (/) in the regex
* Simplified regex per Johannes' feedback
* Sprinkled some newlines into the tests for variety
Changes from v1:
* Updated regex to handle anything after node names instead of
requiring a '{'
* Updated test for boolean relation operators
* Sent out a patch to devicetree spec to document % operator
