hw/misc/iotkit-secctl: Arm IoT Kit security controller initial skeleton
The Arm IoT Kit includes a "security controller" which is largely a
collection of registers for controlling the PPCs and other bits of
glue in the system. This commit provides the initial skeleton of the
device, implementing just the ID registers, and a couple of read-only
read-as-zero registers.
