Also this should go through Shawns tree, so needs to be split out from the series.

This adds the PHY as a new node. The PCI-e controller node gains a phandle property that points to it. There isn't yet any code in the kernel that uses this device's registers, but it will be added for a PCIe PLL erratum workaround.
