This control inverts the signal fed to the right amplifier. This allows to connect one loudspeaker to the two speaker amplifiers in a bridge-tied load configuration getting higher output power.
Is the value chosen for this not going to be a property of how the board is wired up, in which case it should be handled as a DT property rather than varied at runtime?
Not really, in our board we do have a L/R loudspeaker connector and the end user either connects a mono speaker to the left and right channel and enable this control to get more power out of it. Or you can just connect a stereo speaker.
Enabling this control to me does not depend on the board.
