USB: ftdi_sio: add TIAO USB Multi-Protocol Adapter (TUMPA) support

Browse source 
TIAO/DIYGADGET USB Multi-Protocol Adapter (TUMPA) is an FTDI FT2232H
based device which provides an easily accessible JTAG, SPI, I2C, serial
breakout.

FTDI FT2232H provides two serial channels (A and B), but on the TUMPA
channel A is dedicated to JTAG/SPI while channel B can be used for
UART/RS-232: use the ftdi_jtag_quirk to expose only channel B as
a usb-serial interface to userspace.
