intel/skylake: Clean up USB configuration in devicetree
Instead of having many different arrays for USB configuration, with each array containing one bit of information, have one array containing all the information for each port. This way we can put the basic tuning parameters into a structure and then define structures for the basic supported configurations. The existing port definitions are taken from the Skylake HSIO tuning guide. BUG=chrome-os-partner:40635 BRANCH=none TEST=build and boot on glados, verify USB functionality in all ports.
