Fix warnings such:

  disas/nanomips.c:3251:64: warning: format specifies type 'char *' but the argument has type 'int64' (aka 'long long') [-Wformat]
    return img_format("CACHE 0x%" PRIx64 ", %s(%s)", op_value, s_value, rs);
                                            ~~                 ^~~~~~~
                                            %lld

To avoid crashes such (kernel from commit f375ad6a0d):

  $ qemu-system-mipsel -cpu I7200 -d in_asm -kernel generic_nano32r6el_page4k
