hw/npu.c: Add ibm, npu-index property to npu device tree
The PHB slot location code ueses the ibm,phb-index property to find
slot location names. As the NPU is implemented as a different PHB type
it means the phb-index property overlaps with the other PHBs in the
system.
This patch changes the existing usage of phb-index to npu-index which
allows the phb-index property to be assigned a unique value which can
then be matched by the PHB slot location code.
