Luka Kovacic 4dbc107f46 cmd: gpio: Correct do_gpio() return value ...

Use the correct return value in function do_gpio() and update
commands documentation with the return values from command_ret_t enum.

CMD_RET_SUCCESS is returned on command success and CMD_RET_FAILURE is
returned on command failure.

The command was returning the pin value, which caused confusion when
debugging (#define DEBUG).
