powerpc/powernv: Fix M64 resource name in /proc/iomem
The name of PCI root bus's M64 resource isn't initialized properly.
When dumping "/proc/iomem", "<BAD>" is seen for those M64 resources
on PCI root buses.
~# cat /proc/iomem | grep -e "BAD"
3b0000000000-3b0fefffffff : <BAD>
3b1000000000-3b1fefffffff : <BAD>
3c0000000000-3c0fefffffff : <BAD>
3c1000000000-3c1fefffffff : <BAD>
3c2000000000-3c2fefffffff : <BAD>
This fixes the issue by setting the name of PCI root bus's M64
resource to that of PHB's device node full name. With the patch,
no "<BAD>" is seen from "/proc/iomem".
