[CELL] cell: indexing of SPUs based on firmware vicinity properties
This patch links spus according to their physical position using
information provided by the firmware through a special vicinity
device-tree property. This property is present in current version
of Malta firmware.
Example of vicinity properties for a node in Malta:
Node: Vicinity property contains phandles of:
spe@0 [ spe@100000 , mic-tm@50a000 ]
spe@100000 [ spe@0 , spe@200000 ]
spe@200000 [ spe@100000 , spe@300000 ]
spe@300000 [ spe@200000 , bif0@512000 ]
spe@80000 [ spe@180000 , mic-tm@50a000 ]
spe@180000 [ spe@80000 , spe@280000 ]
spe@280000 [ spe@180000 , spe@380000 ]
spe@380000 [ spe@280000 , bif0@512000 ]
Only spe@* have a vicinity property (e.g., bif0@512000 and
mic-tm@50a000 do not have it).
