Re-add in old Endpoint/Pipe workaround for unordered pipes - add new ORDERED_EP_CONFIG compile time option to override the workaround and use the previous behaviour that imposes correct Endpoint/Pipe ordering but produces smaller compiled code.

* \section Sec_SummaryUSBTokens General USB Driver Related Tokens
* This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.
*
* <b>ORDERED_EP_CONFIG</b> - ( \ref Group_EndpointManagement , \ref Group_PipeManagement )\n
* The USB AVRs do not allow for Endpoints and Pipes to be configured out of order; they <i>must</i> be configured in an ascending order to
* prevent data corruption issues. However, by default LUFA employs a workaround to allow for unordered Endpoint/Pipe initialisation. This compile
* time token may be used to restrict the intialisation order to ascending indexes only in exchange for a smaller compiled binary size.
*
* <b>NO_STREAM_CALLBACKS</b> - ( \ref Group_EndpointPacketManagement , \ref Group_PipePacketManagement )\n
* Both the endpoint and the pipe driver code contains stream functions, allowing for arrays of data to be sent to or from the
* host easily via a single function call (rather than complex routines worrying about sending full packets, waiting for the endpoint/
