 score: Fix per-CPU data allocation

 Allocate the per-CPU data for secondary processors directly from the
 heap areas before heap initialization and not via
 _Workspace_Allocate_aligned().  This avoids dependency on the workspace
 allocator.  It fixes also a problem on some platforms (e.g. QorIQ) where
 at this early point in the system initialization the top of the RAM is
 used by low-level startup code on secondary processors (boot pages).

 Update #3507.
