This is a trivial preparatory change which allows checking
the struct dw_pcie_ep_ops .init/.pre_init return values.

Currently only the Layerscape PCIe controller benefits from this as
its ls_pcie_ep_init() may fail in dw_pcie_ep_get_func_from_ep() call,
but the Renesas R-Car Gen5 will benefit from this next.

Since this affects many controller glues and has a huge CC list,
I am sending this separately from the R-Car Gen5 patches.
