rockchip: rk3368: adjust DMC driver for 32/64bit-aware OF_PLATDATA

With the new 32/64bit-aware dtoc, the type of reg is fdt64_t and the
OF_PLATDATA structure layout changes.  This adjusts the DMC driver for
the RK3368 to track these changes.

For the time being (i.e. until regmap_init_mem_platdata works for the
64bit case), we won't use regmap_init_mem_platdata here and simply
access of_plat.reg[] directly.
