[U-Boot] [PATCH][v2] 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
if it cannot find 'usb1', so we need to tell driver do not break until it
scaned all the 'usbx' that the board may have.
