usb: dwc3: gadget: set the OTG flag in dwc3 gadget driver.
This patch is needed in order to pass one test case defined in the OTG Automated Compliance Test specification. Specification location: http://www.usb.org/developers/onthego/otgeh_compliance_plan_1_2.pdf This test case uses PET Tool, and PET Tool is one USB hardware equipment provided by MQP Electronics. Test case id is 6.8.3 B-UUT Bypass Capacitance. We must set this otg flag in order to be able to return OTG descriptor during enumeration, otherwise this test case with failed with below error: "Get OTG descriptor request stalled".
