[PATCH] clk: sunxi: Fix factor clocks usage for sun9i core clocks

[Chen-Yu Tsai]

The sunxi factor clocks usage was changed in

    clk: sunxi: Give sunxi_factors_register a registers parameter

However the sun9i core clocks were not fixed up in that patch,
resulting in breakage. This patch fixes that.

This patch is for 3.20.

A bit of boiler plate code for each clock provider.
Maybe we should add a local helper or something?
