sim: bfin: add OTP output port

This doesn't currently generate any interrupts (as there doesn't appear
to be any documentation to *when* it would even do so), but since the
HRM does say an interrupt line exists between the OTP and the SIC, add
one for completeness sake.  This will make a follow up patch easier.
