Adding support for TP-Link EAP620 HD v1

Ahoy all,
TP-Link has some ceiling mount PoE powered hardware that is aimed at competing with more directly Ubiquiti's Unifi offerings. The EAP620 HD is the lower spec ceiling mount device with only 2 antennas per band. This router is an IPQ8070A based device with fairly generous amounts of RAM ( and ROM The EAP620's does provide SSH access once enabled via the default firmware, which is OpenWRT based. The device is spec'd as follows:
