Subject: [PATCH v3] 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".
