target/arm: Use pointers in crypto helpers
Rather than passing regnos to the helpers, pass pointers to the vector registers directly. This eliminates the need to pass in the environment pointer and reduces the number of places that directly access env->vfp.regs[]. Backports commit 1a66ac61af45af04688d1d15896737310e366c06 from qemu
