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