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

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

For the chipidea usb driver, if the dr_mode is not set, it will set
the device to otg mode by default, so here the dr_mode has not been
set for a long time. 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 QA's testcases.
