Support for rtl88x2eu on ground station

[geofrancis]

I have been testing these on the aircraft side using openHD, they can be found very cheap on aliexpress. the spec says they have 800mw 29db of output. I was going to use these to make a new ground station if it gets supported here.

Facts:

1. There will be Radxa Zero 3W GS image for esp32-cam-fpv in ~one month
2. Radxa Zero 3W groundstation for OpenIPC supports b8812eu2
3. Raspberry PI GS does not work well for OpenIPC because it does not support h265

so I would suggest building Radxa zero 3W + 2x b8812eu2 GS
esp2-cam-fpv does not need high power output on GS, and OpenIPC either, but UE cards are cheap, so why not.
