We model Arm "Subsystems for Embedded" SoC subsystems using generic code which is split into various sub-devices which are configurable by QOM properties to handle the behaviour differences between the SSE subsystems we implement. Currently the only sub-device which needs to change is the IOTKIT_SYSCTL device, and we do this with a mix of properties that directly specify divergent behaviours (eg CPUWAIT_RST) and passing it the SYS_VERSION register value as a way for it to distinguish IoTKit from SSE-200. The "pass SYS_VERSION" approach is already a bit hacky, since the IOTKIT_SYSCTL device has to know that the different part of the register value happens to be bits [31:28]. For SSE-300 this register is renamed SOC_IDENTITY and has a different format entirely, all of whose fields can be configured by the SoC integrator when they integrate the SSE into their SoC, and so "pass SYS_VERSION" breaks down completely. Switch to using a simple integer property representing an internal-to-QEMU enumeration of the SSE flavour. For the moment we only need this in IOTKIT_SYSCTL, but as we add SSE-300 support a few of the other devices will also need to know. We define and permit a value for the SSE-300 so we can start using it in subsequent commits which add SSE-300 support. The now-redundant is_sse200 flag in IoTKitSysCtl will be removed in the following commit.
