    ath79: increase the rfkill debounce interval for TP-Link Archer C7 v2
    
    Due to circuit issue or silicon defect, sometimes the WiFi switch button
    of the Archer C7 v2 can be accidentally triggered multiple times in one
    second. This will cause WiFi to be unexpectedly shut down and trigger
    'irq 23: nobody cared'[1] warning. Increasing the key debounce interval
    to 1000 ms can fix this issue. This patch also add the missing rfkill
    key label.
    
    [1] Warning Log:
    ```
