    Choose a split for DSPARB based on the configured modes for both planes.
    
    Previously, we were attempting to give both planes equal space in the FIFO
    to be fair.  However, larger modes require more fifo space, so split it based
    on the relative HDisplay of the modes.  This should resolve some fifo underrun
    issues with differently-sized displays, or single large ones.
    
    Bug #16169.
    (cherry picked from commit b8ca1c747a679c931267363639fc0bc690cae2d6)

Indeed, reverting that patch on top of 2.4.0 no longer shows the issue.

Cheers,
