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. Signed-off-by: Sander Vanheule <[email protected]>
