We are missing a call to of_node_get. pnv_pci_to_phb_node should call
of_node_get otherwise np's reference count isn't incremented and it might go
away. Rename pnv_pci_to_phb_node to pnv_pci_get_phb_node so it's clear it
calls of_node_get.

Turning snoops on is the last step in CAPP recovery. Sapphire is expected to
have reinitialized the PHB and done the previous recovery steps.
Add mode argument to opal call to do this. Driver can turn snoops off although
it does not currently.

Please consider this patch for stable. Without these defaults, the card could
get in a bad state and require a power cycle to the box.
