USB: Add new FT232H chip to drivers/usb/serial/ftdi_sio.c
appended patch adds support for the new FTDI FT232H chip. This chip is a
single channel version of the dual FT2232H/quad FT4232H, coming with it's
own default PID 0x6014 (FT2232H uses the same PID 0x6010 like FT2232C,
FT4232H has also it's own PID).
The patch was checked on an UM232H module and a terminal program with TX/RX
shorted to that typing in the terminal reproduced the characters.
