usb:dfu:g_dnl: Change number of exported configurations at composite gadget
USB composite gadget (g_dnl) supports only one configuration. Due to that
the corresponding field - bConfigurationValue has been changed.
Moreover more descriptive names were chosen for relevant fields.
Windows XP setup:
- Thesyscon USB Descriptor Dumper
- zadig_xp program for WinUSB installation (which is required by dfu-util)
- dfu-util for windows (version 0.6)
- TRATS target connected via USB hub to test Win XP machine.
Tested at: Trats - Exynos4210
