PCI: dwc: endpoint: Introduce .pre_init() and .deinit()

Renesas R-Car Gen4 PCIe controllers require vendor-specific
initialization before .init().

To use dw->dbi and dw->num-lanes in the initialization code,
introduce .pre_init() into struct dw_pcie_ep_ops. While at it,
also introduce .deinit() to disable the controller by using
vendor-specific de-initialization.

Note that the ep_init in the struct dw_pcie_ep_ops should be
renamed to init later.
