8c40842e4b ftdi_ft4222: Re-order pin numbering and support i2c switch 
First four pins (0 to 3) are now built-in FTDI GPIO/I2C pins
If i2c GPIO expander is detected, next 8 pins (4 to 11) are its GPIO
If i2c switch is detected an extra 4 i2c busses are added

ed0124cc70 mraa_adv_func: Updated signature of gpio_init_internal_replace() 
mraa_adv_func_t->gpio_init_internal_replace() now has mraa_gpio_context
parameter so that override function can access both physical and logical
pin numbers.
