The integration with Zephyr is fairly clean but as MicroPython Hardware API
requires pin ID to be a single value, but Zephyr operates GPIO in terms of
ports and pins, not just pins, a "hierarchical" ID is required, using tuple
of (port, pin). Port is a string, effectively a device name of a GPIO port,
per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer
number of pin with the port (supposed to be in range 0-31).
Example of pin initialization:
pin = Pin(("GPIO_1", 21), Pin.OUT)
(an LED on FRDM-K64F's Port B, Pin 21).
There is support for in/out pins and pull up/pull down but currently
there is no interrupt support.
