Do not config MUSB to highspeed mode if CONFIG_USB_GADGET_DUALSPEED
is not set, in which case Ether gadget only operates in fullspeed.
Note:
This patch is necessary for devices like some siemens boards
that allow only FULL SPEED USB 1.1, e.g. DFU download.

Nack this breaks highspeed mode on boards which use the musb
in host mode, and thus do not set CONFIG_USB_GADGET_DUALSPEED.
