USB: ftdi_sio: add support for FT-X series devices
Add PID 0x6015, corresponding to the new series of FT-X chips
(FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X). They all
appear as serial devices, and seem indistinguishable except for the
default product string stored in their EEPROM. The baudrate
generation matches FT232RL devices.
Tested with a FT201X and FT230X at various baudrates (100 - 3000000).
Sample dmesg:
