ath79: add partial support for Netgear EX7300v2

Hardware -------- SoC: QCN5502 Flash: 16 MiB RAM: 128 MiB Ethernet: 1 gigabit port Wireless No1: QCN5502 on-chip 2.4GHz 4x4 Wireless No2: QCA9984 pcie 5GHz 4x4 USB: none Installation ------------ Flash the factory image using the stock web interface or TFTP the factory image to the bootloader. What works ---------- - LEDs - Ethernet port - 5GHz wifi (QCA9984 pcie) What doesn't work ----------------- - 2.4GHz wifi (QCN5502 on-chip) (I was not able to make this work, probably because ath9k requires some changes to support QCN5502.)
