The AST2700 SSP/TSP firmware accesses Privilege Controller MMIO regions that are not yet implemented in QEMU. This change adds unimplemented MMIO devices for the Privilege Controller blocks and maps them to their corresponding physical addresses in the SSP/TSP address space. These stub devices allow QEMU to safely handle firmware accesses and prevent spurious exceptions, while accurately reflecting the hardware memory map. No functional changes.
