Explicitly set the dr_mode for the dwc3 controller on the
Snow board to host mode. This is required to ensure the
controller is initialized in the right mode if the kernel is
build with USB gadget support.

Kukjin,
I think $subject is -rc material since this issue is seen after commit
508423b ("ARM: exynos_defconfig: enable USB gadget support") which
landed in 3.18.
Best regards,
Javier
