tree nodes to convey SMMU stream IDs in the device
tree.  Fixups are implemented for PCI controllers
initially.

0070459048 pci/layerscape: fix link and class issues to support ls2085a
1. LS2085a provides PCIE_LUT_DBG register rather than PCIE_LDBG
   to show the link status, so the patch fixes it.
2. Increase the delay time to make sure that link training
   has finished.
3. Return invalid value when accessing multi-function device
4. For LS2085a DBI_RO_WR_EN bit is cleared as default, so we
   must set this bit before change DBI register value.

d42bd3453a pci/layerscape: remove unnecessary pcie_layerscape.h
The patch uses the common function name ft_pci_setup to replace
ft_pcie_setup, then removes unnecessary pcie_layerscape.h because
all the functions have been declared in common.h.
