Philippe Mathieu-Daudé 936a236c4e hw/ssi/xilinx_spips: Avoid AXI writes to the LQSPI linear memory
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).
