Subject: [PATCH v2 08/17] PCI: dwc: dra7xx: Assign pp->ops in dra7xx_add_pcie_port() rather than in probe

This matches how other drivers like exynos, imx7, keystone, armada8k,
artpec6, designware-plat, hisi, kirin and spear13xx does it.

This is probably a remainder since when dev and ops were assigned as
members to pp. Since we now assign them as members to struct dw_pcie,
the pp->ops assignment should definitely be in dra7xx_add_pcie_port().

This is also needed to be able to compile host/ep mode specific code
independently.
