[Intel-gfx] [PATCH 19/21] drm/i915: Make bxt_set_cdclk() operate in terms of the current vs target DE PLL vco

From: Ville Syrjälä 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
