Lei Sun found while auditing the code that a CPU write would trigger a NULL pointer dereference. >From UG1085 datasheet [*] AXI writes in this region are ignored and generates an AXI Slave Error (SLVERR). Fix by implementing the write_with_attrs() handler. Return MEMTX_ERROR when the region is accessed (this error maps to an AXI slave error).
