[PATCH v7 2/2] PCI: designware-ep: Move pci_epc_init_notify() inside dw_pcie_ep_init_complete()

[Manivannan Sadhasivam]

Since pci_epc_init_notify() API is getting called right after the
dw_pcie_ep_init_complete() API in the DWC glue drivers, let's move it
inside dw_pcie_ep_init_complete() API as there is no compelling reason to
call it separately.
