Blackfin: SMP: fix cpudata cache setup
After some cache setup reordering changesets, the blackfin_cpudata init was left behind. While cpu0's data was correct, cpu1's data was not. Not that big of a deal as these are only used in the cpuinfo output, but should still be fixed. So move the setup of these fields to the common cache setup function to avoid this happening again in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
