    ath79: correctly define WiFi switch for TL-WR841ND v8
    
    The TL-WR841ND v8 feature a WiFi switch instead of a button.
    This adds the corresponding input-type to prevent booting into
    failsafe regularly.
    
    This has been defined correctly in ar71xx, but was overlooked
    when migrating to ath79. In contrast, the TL-WR842ND v2, which
    has the key set up as switch in ar71xx, actually has a button.
    The TL-MR3420 v2 has a button as well and is set up correctly
    for both targets. (Information based on TP-Link user guide)
    
    Note:
    
    While looking into this, I found that support PR for TL-MR3420 v2
    switched reset button to ACTIVE_HIGH. However, the other two
    device still use ACTIVE_LOW. This seems strange, but I cannot
    verify it lacking the affected devices.
    
    Fixes: FS#2733
    Fixes: 9601d94138de ("add support for TP-Link TL-WR841N/ND v8")
