hw/misc/iotkit-secctl.c: Implement SECMPCINTSTATUS

Browse source 
Implement the SECMPCINTSTATUS register. This is the only register
in the security controller that deals with Memory Protection
Controllers, and it simply provides a read-only view of the
interrupt lines from the various MPCs in the system.
