From: Philippe Mathieu-Daudé <philmd@linaro.org>

The S390X architecture uses big endianness. Directly use
the big-endian LD/ST API.

Mechanical change using:

  $ end=be; \
    for acc in uw w l q tul; do \
      sed -i -e "s/ld${acc}_p(/ld${acc}_${end}_p(/" \
             -e "s/st${acc}_p(/st${acc}_${end}_p(/" \
        $(git grep -wlE '(ld|st)t?u?[wlq]_p' hw/s390x/); \
    done
