gpio_api_1pin testcase verifies following new GPIO API functionality:
- pin active level flags
- input/output configuration flags
- pin drive flags
- gpio_port_*, gpio_pin_* functions
- pin interrupts
The test is using only 1 GPIO pin (defined in DTS as LED0) and relies on
the ability of the driver to configure pin simultanously as in/out.
Drivers that do not allow to configure pins in in/out mode should still
pass the test, however, most of the testcases will be skipped.
The test does not require any modifications to board hardware.
