USB: gadget: use ep5 for bulk-in and ep6 for bulk-out for Blackfin MUSB

Browse source

Normally, the musb uses ep1 as the bidirectional bulk endpoint.  This won't
work on the Blackfin musb as all endpoints (except ep0) are unidirectional.
Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable
for bulk endpoints (which need more like a 512 byte FIFO).  This leaves us
with ep5-ep7 which have 1024 byte FIFOs and can be configured as either
in/out and bulk/interrupt/iso on the fly.
