[v2,0/1] PCI: brcmstb: Fix regression regarding missing PCIe linkup

v2 -- Replace using the condition "bus->number == 1" and instead
      use "pci_is_root_bus(bus->parent)".  Although I initially
      planned to get/enable regulators under and port device,
      this became more complicated for this regression fix.
   -- Corrected the commit message in v1 to say "Root Port DT
      node" rather than "Endpoint DT node".
   -- brcm_pcie_add_bus() now returns 0 if there is an error in
      error in calling pci_subdev_regulators_add_bus().  Instead,
      we dev_err() and turn on our refusal mode instead.
   -- The pci_subdev_regulators_remove_bus() function now calls
      regulator_bulk_free() in addtion to regulator_bulk_disable().
      I noticed that this call was missing after Bjorn had me detail
      the call graph for removing the bus when pcie link-up failed.
   -- Rewrote and added some comments.

v1 -- Original
