Magnus Damm c21af444ea ARM: shmobile: smp: Add function to prioritize DT SMP
Add a function to check if other DT based method is available, and
if so return false to not hook up smp_ops from the machine vector.

This results in that DT-based SMP support has priority over older
C-based smp_ops code, and in case DT-based SMP support code does not
exist in the DTB then the old smp_ops code will still work as-is.
