If you add a select of NOP_USB_XCEIV in the board config option you can
do away with the ifdef.

Is there ever a case, for this board, where you don't want NOP_USB_XCEIV
enabled?

Failing that, add an empty init function to the header file such that
you can always call it even when the option is not enabled. It keeps
the amount of ifdeffery in the code to a minimum.
