drm/i915: fix CB tuning check for ILK+ commit cb0e093162d7b6589c2217a00e2abfef686b32d6 upstream. CB tuning is needed to handle potential process variations that might cause clock jitter for certain PLL settings. However, we were setting it incorrectly since we were using the wrong M value as a check (M1 when we needed to use the whole M value). Fix it up, making my HDMI attached display a little prettier (used to have occasional dots crawl across the display).
