hw/arm/armsse: Make SSE-300 use Cortex-M55

The SSE-300 has a Cortex-M55 (which was the whole reason for us
modelling it), but we forgot to actually update the code to let it
have a different CPU type from the IoTKit and SSE-200.  Add CPU type
as a field for ARMSSEInfo instead of hardcoding it to always use a
Cortex-M33.
