fastmodel: Export the reset signals of the GIC.

These are the "reset" and "po_reset" lines. It seems reasonable that
these are the normal reset and the power on reset signals, but that's
not spelled out in the fast model "lisa" file, nor does it explain
exactly what the difference is between them.
