USB: make EHCI initialize properly on PPC SOCs
Correctly initialize the on-chip EHCI controller on the AMCC PPC440EPx.
Fix "USB 0.0" initialization message, and properly put the controller
into a known state before starting it.
Add "FIXME" comment to the au1xxx bus glue which is doing the same wrong
thing here. (Who maintains that, now that AMD sold off Alchemy?) Remove
some false copyright attributions which were somehow placed in the au1xxx
bus glue then copied into ppc-soc.
