ramips: TP-link archer A6/C6 device tree updates

Set correct GPIO (10) for the WPS button. This matches GPIO settings in
vendor GPL sources. Note that GPL sources also mention a USB indicator
LED (GPIO 13) but the device has neither an external USB port nor a USB LED.

In addition, prefixes (button-, led-) are added to relevant DT entries,
as well as color and function specifications for LEDs.

Closes: #13736
