Subject: [PATCH 115/115] PCI: layerscape: call dw_pcie_setup_rc() in host
initialization
A previous patch moved some Root Complex programming from
dw_pcie_host_init() to dw_pcie_setup_rc() where it belongs,
while the pci-layerscape driver didn't call dw_pcie_setup_rc()
anywhere after that. This patch is to add dw_pcie_setup_rc()
calling in layerscape host initialization to fix ls1012a pci
issue caused by that patch.
Fixes: c49b76f3c613("PCI: designware: Move Root Complex setup
code to dw_pcie_setup_rc()")
