openbios: do not error-out array-bounds warning 

gcc-12.2 produces an apparently wrong warning for this file:

roms/openbios/arch/ppc/qemu/init.c:400:10: error: \
 array subscript 0 is outside array bounds of ‘uint32_t[0]’ {aka ‘unsigned int[]’} \
 [-Werror=array-bounds]
  400 |     *dsi = 0x48002002;
      |     =====^===========

Turn this particular -Werror back into warning. Gcc is apparently wrong here.
