I'd prefer dropping the fbdev driver too, but that would require porting
the SH boards to the DRM driver, and implement DT support for the ARM
board. I don't think anyone is willing to invest time in this, so I'm
fine dropping this driver as the boards are pretty much dead. I would,
however, also drop the fbdev driver in that case.
