Since the previous commit ("exec/memory.h: make devend_memop
"target defines" agnostic") there is a single use of the
DEVICE_HOST_ENDIAN definition in ram_device_mem_ops: inline
it and remove its definition altogether.

In commit 98ed8ecfc9 ("exec: introduce target_words_bigendian()
helper") target_words_bigendian() was matching the definition it
was depending on (TARGET_WORDS_BIGENDIAN). Later in commit
ee3eb3a7ce ("Replace TARGET_WORDS_BIGENDIAN") the definition was
renamed as TARGET_BIG_ENDIAN but we didn't update the helper.
Do it now mechanically using:
$ sed -i -e s/target_words_bigendian/target_big_endian/g \
$(git grep -wl target_words_bigendian)
