usb-serial: wakeup device on input
Currently usb-serial devices are unable to send data into guests with
the xhci controller. Data is copied into the usb-serial's buffer, but
it is not sent into the guest. Data coming out of the guest works
properly. usb-serial devices work properly with ehci.
Have usb-serial call usb_wakeup() when receiving data from the chardev.
This seems to notify the xhci controller and fix inbound data flow.
Also add USB_CFG_ATT_WAKEUP to the device's bmAttributes. This matches
a real FTDI serial adapter's bmAttributes.
