ichx_gpio_check_available() returns either 0 or -ENXIO depending on whether
the given GPIO is available or not. However, callers of this function treat
the return value as boolean:
...
if (!ichx_gpio_check_available(gpio, nr))
return -ENXIO;
which erroneusly fails when the GPIO is available and not vice versa.
Fix this by making the function return boolean as expected by the callers.
