preonic/rev3{,_drop}: Fix layouts with 2u keys (#21114)

Apparently layouts with 2u keys were not correctly converted into the
`info.json` format (the old C layout macros used the arguments for such
keys multiple times to cover all possible 1u locations; this is not
supported in `info.json`, and the single matrix location for 2u keys was
chosen incorrectly in some cases).  Fix the layout definitions to match
the real PCB wiring.
