Nysal Jan K.A 8555383730 powerpc/topology: Check if a core is online ...

[ Upstream commit 227bbaabe6 ]

topology_is_core_online() checks if the core a CPU belongs to
is online. The core is online if at least one of the sibling
CPUs is online. The first CPU of an online core is also online
in the common case, so this should be fairly quick.
