clk: sunxi-ng: sun5i: Fix bit offset of audio PLL post-divider
The post-divider for the audio PLL is in bits [29:26], as specified in the user manual, not [19:16] as currently programmed in the code. The post-divider has a default register value of 2, i.e. a divider of 3. This means the clock rate fed to the audio codec would be off. This was discovered when porting sigma-delta modulation for the PLL to sun5i, which needs the post-divider to be 1. Fix the bit offset, so we do actually force the post-divider to a certain value.
