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.
in 3.8. The people we asked to test that patch continued to report
issues afterwards, so maybe we need to boost that value a little more,
or maybe we didn't have the same root cause.
What would be useful would a debugfs entry for us to see what values
were changed in the BIOS.
