 * The Audio PLL is supposed to have 4 outputs: 3 fixed factors from

 * 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
