Let's see... according to Ubiquiti's web page, it seems that "LiteAP AC" is a family of devices with two members: LAP-120 and LAP-GPS.
The LAP-120 was previously called LiteBeam 5AC 16 120 (LBE-5AC-16-120), but then it was renamed. Still there are some references on the website (https://dl.ubnt.com/datasheets/LiteBeam/LiteBeam_DS.pdf), where you can see it has exactly the same characteristics. I believe the hwdata pages should be merged, and explain this on device page.
The LAP-GPS appeared later, and it doesn't have any entry in the ToH.
Regarding the devicepages, I don't know whether it makes sense to have LAP-120 and LAP-GPS (whenever it is added) in two different pages, or have a common one for the LiteAP AC family (e.g.: https://openwrt.org/toh/ubiquiti/powerbeam_5ac). You probably have more criteria than me.
