target/arm: Add dummy needed functions to M profile vmstate subsections
Currently the migration code incorrectly treats a subsection with no .needed function pointer as if it was the subsection list terminator -- it is ignored and so is everything after it. Work around this by giving various M profile vmstate structs a 'needed' function that always returns true. We reuse m_needed() for this, since it's always true here.
