All clock specific data will end up in struct vdso_clock and in struct vdso_time_data there will be array of it. By now, vdso_clock is simply a define which maps vdso_clock to vdso_time_data. To prepare for the rework of the data structures, replace the struct vdso_time_data pointer with struct vdso_clock pointer whenever applicable. No functional change.
