[PATCH v3 01/11] usb: dwc3-omap: use device_for_each_child to handle child removal

[Kishon Vijay Abraham I]

Used device_for_each_child() to handle child device (dwc3 core) removal
during devexit of dwc3 omap. This is in preparation for creating the child
devices from subnode of dwc3 omap glue using of_platform_populate.
