USB: fix usb-serial/ftdi build warning
Fix annoying build warning: drivers/usb/serial/ftdi_sio.c:890: warning: enumeration value `FT232RL' not handled in switch Also add logic to detect FT232R chips (version 6.00, usb 2.0 full speed), so that case isn't completely useless. (NOTE: FT232RL and FT232RQ are the same chip in different packages: L is SSOP, Q is QFN.)
