[CELL] spufs: extension of spu_create to support affinity definition
This patch adds support for additional flags at spu_create, which relate to the establishment of affinity between contexts and contexts to memory. A fourth, optional, parameter is supported. This parameter represent a affinity neighbor of the context being created, and is used when defining SPU-SPU affinity. Affinity is represented as a doubly linked list of spu_contexts.
