[PATCH] checkpatch: suppress MAINTAINERS warning for newly added device tree files

[Ahmad Fatoum]

Linux ships with thousands of device trees and device tree maintainers
have indicated that they don't want to see hundreds of maintainer entries
added for them[1].

Yet, checkpatch.pl keeps warning about it, which is annoying:

  WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?

Avoid this by making the warning conditional on the file not having a
.dts or .dtsi extension.
