Let's assigne slot numbers, ep-gpios and clkreq used by PCIe
on evb board as well the PHY node here. Note that we still
disable them as the auto training of PCIe link will make the
kernel use more time to boot if there are no any devices there.

with both the pcie-controller and -phy now being in maintainer trees, I've
applied all 3 dts patches to my dts64 branch for 4.9
Thanks
