sim: bfin: respect the port level on signals to the SIC 

The SIC latches ints from peripherals to the CEC, but the peripherals
need to be able to tell the SIC when to stop.  So use the incoming level
to figure out when to set the int bits and when to clear it.

* dv-bfin_sic.c (bfin_sic_port_event): New helper function.
(bfin_sic_52x_port_event, bfin_sic_537_port_event,
bfin_sic_54x_port_event, bfin_sic_561_port_event): Include level
in the trace output, and call the new bfin_sic_port_event func.

* dv-bfin_gpio.c (bfin_gpio_ports): Add p15.
