ath79: Add support for TP-Link Archer C25 v1

The TP-Link Archer C25 is a low-cost dual-band router.

Specification:

- CPU: Atheros QCA9561 775 MHz
- RAM: 64 MB
- Flash: 8 MB
- Wifi: 3x3 2.4 GHz (integrated), 1x1 5 GHz QCA9887
- NET: 5x 10/100 Mbps Ethernet

Some LEDs are controlled by an additional 74HC595 chip, but not
all of them as e.g. for the C59.
