hw/misc/iotkit-sysinfo.c: Implement SYS_CONFIG1 and IIDR
For SSE-300, the SYSINFO register block has two new registers:
* SYS_CONFIG1 indicates the config for a potential CPU2 and CPU3;
since the SSE-300 can only be configured with a single CPU it
is always zero
* IIDR is the subsystem implementation identity register;
its value is set by the SoC integrator, so we plumb this in from
the armsse.c code as we do with SYS_VERSION and SYS_CONFIG
