[PATCH 049/114] clk: spacemit: ccu_ddn: convert from round_rate() to determine_rate()

[Yixun Lan]

Hi Brian,

  Thanks for doing this

  I will give my rb to 49-51 for SpacemiT, and here we face same
issue as Krzysztof did for samsung, to avoid potential conflicts
we will route the clk patches through SpacemiT SoC tree..
