aarch64: vp9itxfm: Use a single lane ld1 instead of ld1r where possible
The ld1r is a leftover from the arm version, where this trick is
beneficial on some cores.
Use a single-lane load where we don't need the semantics of ld1r.
This is cherrypicked from libav commit
ed8d293306e12c9b79022d37d39f48825ce7f2fa.
