 score: Remove CPU_PARTITION_ALIGNMENT

 Use the CPU_SIZEOF_POINTER alignment instead.  The internal alignment
 requirement is defined by the use of Chain_Node (consisting of two
 pointers) to manage the free chain of partitions.

 It seems that previously the condition

   CPU_PARTITION_ALIGNMENT >= sizeof(Chain_Node)

 was true on all CPU ports.  Now, we need an additional check.

 Update #3482.
