hw/arm/armsse: Add SSE-300 support
Now we have sufficiently parameterised the code, we can add SSE-300 support by adding a new entry to the armsse_variants[] array. Note that the main watchdog (unlike the s32k watchdog) in the SSE-300 is a different device from the CMSDK watchdog; we don't have a model of it so we leave it as a TYPE_UNIMPLEMENTED_DEVICE stub.
