Fixed power plane clearance on VUSB.
Added duplicate V1P8 and front end VCCIO planes to pair with the other ground plane. Otherwise, it's not really 50 Ohms, is it?
Lots of other power plane tweaks and some control signal routing.
Fixed up USB 2.0 DP/DM routing into ESD device.
Removed VREF planes in trade for point-to-point routing, which allows larger VCCIO planes.
