MLK-11457-04 ARM: dts: imx6qdl: add uart3 pad set for sabreauto board
Add imx6qdl-sabreauto board uart3 DTE pad set. To avoid a flood of
dts files, there comment out DTE pinctrl set. If user want to test
DTE mode, it needs to rebuild the DTB file.
(cherry picked from commit dc6028b08c6bd718d57866a1714f3977ba7820d3)
