sim: bfin: add support for glued SIC interrupt lines

The BF537 family glues a bunch of peripherals into single interrupt lines
that run into the SIC.  To model this same behavior in the sim, we need to
use the glue-or device, and in order to use that, we need to tweak things
a bit in the mach code to allow declaring of these new devices.
