[U-Boot] [PATCH] Fix usb buffer size for large descriptor of devices

[Nicolas Chauvet]

scanning bus 0 for devices...
usb_get_configuration_no: failed to get descriptor - too long: 943

This was experienced on toshiba ac100 aka paz00, when discovering
the webcam.

This patch is probably wrong, as it raise the buffer for all usb.
Instead it could probably be raised only per target system of maybe
per kind of devices
