gpio: make gpiod_direction_output take a logical value
The documentation was not clear about whether
gpio_direction_output should take a logical value or the physical
level on the output line, i.e. whether the ACTIVE_LOW status
would be taken into account.
This converts gpiod_direction_output to use the logical level
and adds a new gpiod_direction_output_raw for the raw value.
