Note that it wasn't updated because this driver was not used on Renesas
ARM platforms, due to the lack of DT bindings and DT support, so it
didn't make sense to make it selectable.

Indeed, this driver should work with the R-Mobile A1 (which made it
into orbit, so we could call it the first member of R-Space ;-) and
SH-Mobile AG5 SoCs. The major blocker is the lack of DT bindings.
