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.
