* 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
* match the clock names.
