  It makes sense to enable CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT by default
(when possible by dependencies) to take advantages of all 256 PCI buses on
each PCI domain, like it is already on all other kernel architectures.

Fixes: 566356813082 ("powerpc/pci: Add config option for using all 256 PCI buses")

 	  By default on PPC32 were PCI bus numbers unique across all PCI domains.
 	  So system could have only 256 PCI buses independently of available
