[U-Boot] [PATCH][v3] powerpc/85xx: enable USB2 gadget mode for corenet ds board

[Shaohui Xie]

to make USB2 worked in gadget mode, we need to set it's 'dr_mode' to
'peripheral' in hwconfig, but driver starts scan from 'usb1', it'll break
out if it cannot find 'usb1', so drop the 'else' clause to make driver scan
all the 'usbx'.

2. drop #define CONFIG_SYS_USB_DEVICE.
