This is not usable for rk3066/rk3188 and OF_PLATDATA in combination with
c code as there's no guaranty that other models have this property in
the dtplat structure.

It's about finding a solution for disabling fifo-mode and OF_PLATDATA.

There's also a V2 with a more generic approach. Could you have a look at
it as well. Whatever which method is preferred.

#if CONFIG_IS_ENABLED(OF_PLATDATA)
	struct dtd_rockchip_rk3288_dw_mshc dtplat;
#endif
