amd/stoneyridge: Add USB ASL for D0/D3cold
Add methods, and call them, for transitioning EHCI and xHCI to D0 or D3cold. Add device objects necessary for waking the system via USB. In order for USB to wake the system, it must be in the D3cold state. Then on resume, its firmware must be reloaded. This code relies heavily on AMD's FchCarrizo.asl (delivered in NDA PI package), and has been modified to fit the coreboot ASL names. In addition, AMD's methodology is to generate a SW SMI for saving/restoring certain settings. This has been ported into U3D0 and U3D3, as the necessary registers are now publicly documented.
