Make bxt_set_cdclk() more readable by looking at current vs. target DE PLL vco to determine if the DE PLL needs disabling and/or enabling. We can also calculate the CD2X divider simply as (vco/cdclk) instead of depending on magic numbers. The magic numbers are still needed though, but only to map the supported cdclk frequencies to corresponding DE PLL frequencies. Note that w'll now program CDCLK_CTL correctly even for the bypass case. Actually the CD2X divider should not matter in that case since the hardware will bypass it too, but the "decimal" part should matter (if we want to do gmbus/aux with the bypass enabled).
