      nfp: get_phys_port_name for representors and SR-IOV reorder
      
      This series starts by making the error message if FW cannot be located
      easier to understand.  Then I move some functions from PCI probe files
      into library code (nfpcore) where they belong, and remove one function
      which is never used.
      
      Next few patches equip representors with nfp_port structure and make
      their NDOs fully shared (not defined in apps), thanks to which we can
      easily determine which netdevs are NFP's by comparing the NDO pointers.
      
      10th patch makes use of the shared NDOs and nfp_ports to deliver
      netdev-type independent .ndo_get_phys_port_name() implementation.
      
      Patches 11 and 12 reorder the nfp_app SR-IOV callbacks with enabling
      SR-IOV VFs.  Unfortunately due to how PCI subsystem works we can't
      guarantee being able to disable SR-IOV at exit or that it will be
      disabled when we first probe...  We must therefore make sure FW is
      able to deal with being loaded while SR-IOV is already on.
      
      Patch 13 fixes potential deadlock when enabling SR-IOV happens at
      the same time as port state refresh.  Note that this can't happen
      at this point, since Flower doesn't refresh ports... but lockdep
      doesn't know about such details and we will have to deal with this
      sooner or later anyway.
      
      Last but not least a new Kconfig is added to make sure those who
      don't care about flower offloads have a way of not including the
      code in their kernels.  Thanks to nfp_app separation this costs us
      a single ifdef and excluding flower files from the build.
