When the initialization of usb3 phy fails, when enabled in the system
the dwc3_probe deferral is further qualified by the maximum speed.
In devices such as dra7xx, there are multiple dwc3 instances where the
maximum_speed is different between the instances.
This patch depends on http://www.spinics.net/lists/linux-usb/msg88627.html
