opal_pci_get_phb_capi_mode() returns OPAL_PHB_CAPI_MODE_CAPI if the PHB is in CAPI mode, and OPAL_PHB_CAPI_MODE_PCIE if it isn't.
We're going to use this call to determine if a PHB requires a complete reset during initialisation in order to disable CAPI mode (on sufficiently new skiboots that support this).
