deinit() callback was solely introduced for the pcie-rcar-gen4 driver where it is used to do platform specific resource deallocation. And this callback is called right at the end of the dw_pcie_ep_exit() API. So it doesn't matter whether it is called within or outside of dw_pcie_ep_exit() API. So let's remove this callback and directly call rcar_gen4_pcie_ep_deinit() in pcie-rcar-gen4 driver to do resource deallocation after the completion of dw_pcie_ep_exit() API in rcar_gen4_remove_dw_pcie_ep(). This simplifies the DWC layer.
