Mark Kettenis dbc5e28604 pci: Make Rockchip PCIe voltage regulators optional 
The vpcie*-supply properties are optional and these are absent on
boards like the ROCKPro64 and Firefly RK3399 where the voltage is
supplied by always-on regulators that are already enabled upon
boot.  Make these regulators optional and properly check their
presence before attempting to enable them.

Makes PCIe work on un U-Boot on the boards mentioned above.
