Ok, I hadn't noticed at all that it was broken in mainline already,
as the three mmp defconfigs do not use drivers/clk/ at all but instead
rely on arch/arm/mach-mmp/clock*.c instead, which has a separate
implementation.

With the move to multiplatform, the choice goes away and we use the
common clock implementation unconditionally.
