target/loongarch: Replace MO_TE -> MO_LE

target/loongarch: Replace MO_TE -> MO_LE

We only build the LoongArch target using little endianness
order, therefore the MO_TE definitions expand to the little
endian one. Use the latter which is more explicit.

Mechanical change running:

  $ sed -i -e s/MO_TE/MO_LE/ \
        $(git grep -wl MO_TE target/loongarch/)
