clk: sunxi-ng: sun4i: Set VCO and PLL bias current to lowest setting 
The default mid-level PLL bias current setting interferes with sigma
delta modulation. This manifests as decreased audio quality at lower
sampling rates, which sounds like radio broadcast quality, and
distortion noises at sampling rates at 48 kHz or above.

Changing the bias current settings to the lowest gets rid of the
noise.

Fixes: de34485191 ("clk: sunxi-ng: sun4i: Use sigma-delta modulation
		      for audio PLL")

* 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
