[CELL] cell: add vicinity information on spus
This patch adds affinity data to each spu instance. A doubly linked list is created, meant to connect the spus in the physical order they are placed in the BE. SPUs near to memory should be marked as having memory affinity. Adjustments of the fields acording to FW properties is done in separate patches, one for CPBW, one for Malta (patch for Malta under testing).
