Allwinner sunXi SoCs clock changes

This contains the clk driver parts of the "[PATCH v3 00/13] clk: sunxi:
add PLL5 and PLL6 support" series. It adds support for PLL4/5/6 and
mod0 clocks on most sunxi platforms. Additionally, it contains "[PATCH
1/4] clk: sunxi: Allwinner A20 output clock support" (v2) from Chen-Yu
Tsai, which adds support for output clocks present on A20.
