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. Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
