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 Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de> Cc: "Egli, Samuel" <samuel.egli@siemens.com>
