This patch series makes it possible to use FT2232H ACBUS[7:0]
pins as gpio pins from sandbox barebox.
I have tested output gpio functionality by connecting
a LED to ACBUS[0] and lightening it with gpio_direction_output
and gpio_set_value barebox commands.
Also I have performed input test with ACBUS[0] -> ACBUS[1] loopback.
The main goal of adding gpio functionality to sandbox barebox
is using it for connecting real i2c and spi devices to sandbox barebox
(not tested yet).

sandbox: avoid symbol conflict for {open,read,close}dir
sandbox: add gpio support with libftdi1
