[U-Boot] [PATCH 2/3] rockchip: rk3128: add ofdata_to_platdata() callback for driver

[Kever Yang]

Parse of data in dedicate api instead of in probe().

The clk_set_rate() may be called before the clk driver is probed,
after core support set default clock.
This patch fix system abort issue since:
f4fcba5 clk: implement clk_set_defaults()
