hw/ssi/xilinx_spips: fix an out of bound access
The spips, qspips, and zynqmp-qspips share the same realize function
(xilinx_spips_realize) and initialize their io memory region with different
mmio_ops passed through the class. The size of the memory region is set to
the largest area (0x200 bytes for zynqmp-qspips) thus it is possible to write
out of s->regs[addr] in xilinx_spips_write for spips and qspips.
This fixes that wrong behavior.
