Subject: [PATCH V4 2/7] IB/hfi1: Use pci_try_reset_bus() for initiating pci secondary bus reset

Getting ready to hide pci_reset_bridge_secondary_bus() from the drivers.
pci_reset_bridge_secondary_bus() should only be used internally by the
PCI code itself.

Other drivers should rely on higher level pci_try_reset_bus() API.
