usb-ehci: trace mmio and usbsts
This patch starts adding trace support to ehci. It traces updates of the status register (USBSTS), mmio access and controller reset. It also adds functions to set and clear status register bits and puts them in use everywhere. Some DPRINTF's are dropped in favor of the new tracepoints. No change in behavior.
