    target/105753: Fix ICE in add_clobbers due to extra PARALLEL in insn.

    This patch removes the superfluous parallel in [u]divmod patterns in
    the AVR backend.  Effect of extra parallel is that add_clobbers reaches
    gcc_unreachable() because the clobbers for [u]divmod are missing.
    If an insn has multiple parts like clobbers, the parallel around the
    parts of the insn pattern is implicit.
