The divider of the audio PLL has an offset of 1.
Fix this in the driver.

Applied, thanks!
So even with this patch applied, the audio is still slow and off pitch.
It's even worse without this patch...

Maybe it's time we added a special class of clks for the audio PLL
to deal with sigma-delta modulation of the divider?
I'm not sure how feasible that would be and what it would look like,
but you can give it a shot yes.
