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.

sim: bfin: push SIC mappings to device tree

The machs.c file is the best place for holding cpu-specific details, so
restructure the way the SIC manages its ports to do just that.  Now the
SIC's have a standard set of input pins and the different line routing
from peripherals is kept in the device tree only.  This better models
the hardware where the SIC doesn't care about the exact peripheral that
is sending it stuff, just which input pin it gets it on.

sim: fix minor --sysroot mem leak

The current --sysroot parsing attempts to keep from leaking memory by
treating the empty string specially (sine this is the initial value),
but it ends up leaking memory when the arg is an empty string.  So if
someone uses --sysroot "", the old value is leaked, as is the new one.
