Ben Widawsky 31643d54a7 drm/i915: Workaround to bump rc6 voltage to 450 ... BIOS should be setting the minimum voltage for rc6 to be 450mV. Old or buggy BIOSen may not be doing this, so we correct it for them. Ideally customers should update the BIOS as only it would know the optimal values for the platform, so we leave that fact as a DRM_ERROR for the user to see. Unfortunately this isn't fixing any of the issues it was targeted to fix, but it is documented that we must do it.
