    realtek: debounce reset key for Zyxel GS1900
    
    When the reset button is next to the SFP cages, I2C operations on the
    modules might cause interference on the button's GPIO line. Add a
    debounce-interval of 5 times the poll-interval to ensure the line is
    actually stable for some time and not just glitching.
    
    This squashes commit 4357f32d41eb ("realtek: debounce reset key for
    Zyxel GS1900") and commit 777c6106ed4e ("realtek: move debounce-interval
    to correct node").
