USB: serial: generalise generic read implementation
Add process_read_urb to usb_serial_driver so that a driver can rely on
the generic read (and throttle) mechanism but still do device specific
processing of incoming data (such as adding tty_flags before pushing to
line discipline).
The default generic implementation handles sysrq for consoles but
otherwise simply pushes to tty.
