hw/arm/iotkit: Refactor into abstract base class and subclass
The Arm SSE-200 Subsystem for Embedded is a revised and
extended version of the older IoTKit SoC. Prepare for
adding a model of it by refactoring the IoTKit code into
an abstract base class which contains the functionality,
driven by a class data block specific to each subclass.
(This is the same approach used by the existing bcm283x
SoC family implementation.)
