USB is only used for CCD. USB should not be enabled as a wakeup source unless a debug accessory is detected, because that is the only USB traffic we care about. The rest may be from other sources like the HID interface or something else using those signals. This change disables the utmi wake source when the debug accessory is attached and enables it when it is connected. BUG=chrome-os-partner:54796 BRANCH=none TEST=manual The SPI_CS_L pin still gets triggered and will wake up cr50 before usb so disable wake up pins as a wakeup source. Verify Cr50 goes to sleep and plugging in a SuzyQ will wake it up and after removing it Cr50 will go back to sleep.
