arm: Fix to pass typed pointer with a cast to %p

This patch fixes the below compilation error with a static_cast.

../src/arm/disasm-arm.cc:689:72:
    error: format specifies type 'void *' but the argument has type
    'v8::internal::byte *' (aka 'unsigned char *') [-Werror,-Wformat-pedantic]
    out_buffer_pos_ += SNPrintF(out_buffer_ + out_buffer_pos_, "%p", addr);
