without ep-gpios defined u-boot does not initialise PCIe
rockchip_pcie pcie@f8000000: failed to find ep-gpios property

additionally set max-link-speed and pinctrl-names for completeness

with this patch and the ones from Florian Klink applied to the dts
file in u-boot sata drives show up in both u-boot and linux
