Subject: [PATCH 01/37] PCI: dwc: dra7xx: Group all host related setup in add_pcie_port

commit 150645b94348 ("PCI: dra7xx: Move struct pcie_port
setup to probe function") moved host related setup to the probe
function. However instead of cluttering the probe function with
host related setup, group all host related setup in add_pcie_port
function. This way when endpoint support is added, all the
endpoint related setup can be added in a separate function.
