ar71xx: 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.
