Chen-Yu Tsai de34485191 clk: sunxi-ng: sun4i: Use sigma-delta modulation for audio PLL 
The audio blocks require specific clock rates. Until now we were using
the closest clock rate possible with integer N-M factors. This resulted
in audio playback being slightly slower than it should be.

The vendor kernel gets around this (for newer SoCs) by using sigma-delta
modulation to generate a fractional-N factor. As the PLL hardware is
identical in most chips, we can back port the settings from the newer
SoC, in this case the H3, onto the A10 and A20.

* The Audio PLL is supposed to have 4 outputs: 3 fixed factors from
* the base (2x, 4x and 8x), and one variable divider (the one true
* pll audio).
*
* With sigma-delta modulation for fractional-N on the audio PLL,
* we have to use specific dividers. This means the variable divider
* can no longer be used, as the audio codec requests the exact clock
* rates we support through this mechanism. So we now hard code the
* variable divider to 1. This means the clock rates will no longer
