Currently ehci-platform is only used in combination with devicetree when used with some Via socs. By extending it to (optionally) get clks and a phy from devicetree, and enabling / disabling those on power_on / off, it can be used more generically. Specifically after this commit it can be used for the ehci controller on Allwinner sunxi SoCs. Since ehci-platform is intended to handle any generic enough non pci ehci device, add a "usb-ehci" compatibility string. There already is a usb-ehci device-tree bindings document, update this with clks and phy bindings info. Although actually quite generic so far the via,vt8500 compatibilty string had its own bindings document. Somehow we even ended up with 2 of them. Since these provide no extra information over the generic usb-ehci documentation, this patch removes them. The ehci-ppc-of.c driver also claims the usb-ehci compatibility string, even though it mostly is ibm,usb-ehci-440epx specific. ehci-platform.c is not needed on ppc platforms, so add a !PPC_OF dependency to it to avoid 2 drivers claiming the same compatibility string getting build on ppc.
