pc-bios/s390-ccw: add -Wno-array-bounds

The option generates a lot of warnings for integers casted to pointers,
for example:

/home/pbonzini/work/upstream/qemu/pc-bios/s390-ccw/dasd-ipl.c:174:19: warning: array subscript 0 is outside array bounds of ‘CcwSeekData[0]’ [-Warray-bounds]
  174 |     seekData->cyl = 0x00;
      |     ~~~~~~~~~~~~~~^~~~~~
