[U-Boot] [U-Boot, v3, 19/20] clk: rockchip: clk_rk3288: Implement "assign-clock-parent" and "assign-clock-rate"

[Philipp Tomsich]

> The RK3288 CRU-node assigns rates to a number of clocks that are not
> implemented in the RK3288 clock-driver (but which have been
> sufficiently initialised from rkclk_init()): for these clocks, we
> implement the gmac clock set parent, but simply ignore the
> others' set_rate() operation and return 0 to signal success.
