[PATCH v2] ARM: dts: nxp: imx6qdl-sabresd: add dr_mode to usbotg

[Hui Wang <hui.wang@canonical.com>]

Currently there are 3 type of boards (imx6q|imx6qp|imx6dl-sabresd)
based on imx6qdl-sabresd.dtsi, they all do not set the dr_mode for
usbotg device node. The chipidea usb driver will configure it to otg
mode by default if the dr_mode is not set, but some testcases need to
parse the dr_mode from DT and decide the follow-up test strategy, here
set the dr_mode to otg explicitly for these 3 imx6qdl-sabresd based
boards.

in the v2:
 adding the dr_mode in imx6qdl-sabresd.dtsi rather than imx6qdl.dtsi
