Subject(resend) [PATCH 2/4] blackfin: don't touch cpu_possible_map and cpu_present_map directly
Date
We plan to remove cpu_possible_map and cpu_present_map later and we
have proper init_cpu_possible() and init_cpu_present() APIs.

Therefore this patch rewrites platform_init_cpus and platform_prepare_cpus
by their APIs.
