Subject: PCI: layerscape: Refactor ls1021_pcie_host_init()
Git-commit: fa92dba92c0026a8378085dbeab8a1d8ad8476c6
Patch-mainline: v4.14-rc1
References: fate#326536, fate#326532
ls1021_pcie_host_init() duplicated the code in the generic
ls_pcie_host_init(). Call ls_pcie_host_init() instead of duplicating the
code.
