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:
```
