usb: gadget: configfs: OS String support
Add handling of OS String extension from the configfs interface. A directory "os_desc" is added at the top level of a gadget's directories hierarchy. In the "os_desc" directory there are three attributes: "use", "b_vendor_code" and "qw_sign". If "use" contains "0" the OS string is not reported to the host. "b_vendor_code" contains a one-byte value which is used for custom per-device and per-interface requests. "qw_sign" contains an identifier to be reported as the "OS String" proper.
