PCI: rcar: Add R-Car gen3 PHY support

Browse source

On R-Car gen3 SoCs the PCIe PHY has its own register region, thus we
need to add the corresponding code in rcar_pcie_hw_init_gen3() and call
devm_phy_optional_get() at the driver's probing time, so that the
existing R-Car gen3 device trees (not having a PHY node) would still
work (we only need to power up the PHY on R-Car V3H).
