[PATCH V5 6/8] USB: f81232: clarify f81232_ioctl()

[Peter Hung <hpeter@gmail.com>]

We extract TIOCGSERIAL section in f81232_ioctl() to f81232_get_serial_info()
to make it clarify

The f81232_set_mctrl() replace set_control_lines() to do MCR control
so we clean-up the set_control_lines() function.
