libpayload: usb: Unify USB speed between XHCI stack and USB core
This patch removes the confusing concept of a special "xhci_speed" with a different numeric value from the usual speed used throughout the USB core (except for the places directly interacting with the xHC, which are explicitly marked). It also moves the MPS0 decoding function into the core and moves some definitions around in preparation of later changes that will make the stack SuperSpeed-ready. It makes both set_address implementations share a constant for the specification-defined SetAddress() recovery delay and removes pointless additional delays from the non-XHCI version.
