#1304396 — [RFC PATCH 1/2] clk: rockchip: rk3036: Add to 100MHz integer multiples of cpu freq table

We need the cpu changing freqs capability, and considering that emac ref
which is need 50MHz might is under the APLL, meanwhile, we don't need
too many freqs because it may spend more time to find the correct freq.
Therefore, we should add 100MHz integer multiples cpu freqs for emac.
