[PATCH v2 2/3] ARM: shmobile: r8a7779: Rely on DT for SMP CPU info

Remove r8a7779 specific ->smp_init_cpus() callback and
instead of relying on shmobile_smp_init_cpus() simply
use DT for CPU core information.
Based on work for the sh73a0 by Magnus Damm.

Run-time dependency on "ARM: shmobile: marzen: Switch to DT_MACHINE_START".
