Adding OpenWrt support for Mikrotik hAP ac 3 [RBD53iG-5HacD2Hn]

First of all, you are in the wrong topic.

Second, you loaded the wrong image, with the wrong method. The Hap AC3 is not completely the same as at Hap AC3 LTE6 kit. You need to recover to ROS version 6 via netboot, and then start again based on the commit message of the LTE6 kit and NOT the one you mentioned.
