PCI: cadence-ep: Introduce cdns_pcie_ep_disable() helper for cleanup
Introduce the helper function cdns_pcie_ep_disable() which will undo the
configuration performed by cdns_pcie_ep_setup(). Also, export it for use
by the existing callers of cdns_pcie_ep_setup(), thereby allowing them
to cleanup on their exit path.
