Subject: [PATCH 11/17] devtree: Add chip-id from CPU node
Add chip-id from CPU node into the configuration if available. CPU's are
behind the CHIP on Power systems. By adding chip-id it helps to map what cpus
are sitting behind which chip.
Sample output:
*-cpu:10
description: POWER8E (raw), altivec supported
product: 00FX746 FRU# 00FX522
physical id: 176
bus info: cpu@10
version: 2.1 (pvr 004b 0201)
...
configuration: chip-id=1 threads=8
