Interface 1 on this device isn't for option to bind to otherwise an oops
on usb_wwan with log flooding will happen when accessing the port:

tty_release: ttyUSB1: read/write wait queue active!

It doesn't seem to respond to QMI if it's added to qmi_wwan so don't add
it there - it's likely used by the card reader.

FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would only report this limitation for CS6 to dmesg and fail to reflect this fact to tcgetattr. This patch reverts the unsupported CSIZE setting and reports the fact with less severance to dmesg for both CS5 and CS6. To test the patch it's sufficient to call stty -F /dev/ttyUSB0 cs5 which will succeed without the patch and report an error with the patch applied. As an additional fix this patch ensures that the control request will always include a data bit size.

This patch fixes the CS5 setting on the PL2303 USB-to-serial devices. CS5 has a value of 0 and the CSIZE setting has been skipped altogether by the enclosing if. Tested on 3.11.6 and the scope shows the correct output after the fix has been applied. Tagged to be added to stable, because it fixes a user visible driver bug and is simple enough to backport easily.
