From: Sameer Nanda <snanda@xxxxxxxxxxxx> This is a regression from the initial i915 PC7 sandbox branch to the one that finally got merged. It is resulting in increased power draw of ~1W due to low PC7 residency. Pulling this in as a CHROMIUM fix for now till it gets resolved upstream. BUG=chrome-os-partner:20840 TEST=Run "intel_reg_read 0x45270" command on a falco. It should come back with "0x45270 : 0x1C00A7".
