rockchip: timer: add OF_PLATDATA support for dw-apb-timer
The Rockchip rk3066 SoC has 3 dw-apb-timer nodes.
U-boot is compiled with OF_PLATDATA TPL/SPL options,
so add OF_PLATDATA support for the dw-apb-timer.
Also change driver name to be able to compile with
U-boot scripts. No reset OF_PLATDATA support was added,
because the rk3066 nodes don't need/have them.
