include: zephyr: dt-bindings: gpio: Add arduino-header-r3 defines
To make the pin names of the Arduino header easier to understand, we will introduce a macro definition for the pin names. We will use this to update the definition of `arduino_uno_r4`. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
