ft2232_spi: Add support for Tin Can Tools Flyswatter/Flyswatter 2

Browse Source 
The Tin Can Tools Flyswatter and Flyswatter 2 have a FT2232H
with a  JTAG interface wired to port A. The buffers that drive the
JTAG pins need to be enabled with an nOE signal from the
FT2232H ADBUS6 and ADBUS7 pins.

Flyswatter has an ARM-14 JTAG interface and Flyswatter 2 has
an ARM-20 JTAG interface.
