This patch set enables BACO CI and VI asics. BACO is Bus Active Chip Off. It allows us to turn off the GPU while still keeping the bus interface up, so the device does not disappear from the system. PowerXpress and Hybrid Graphics laptops support BOCO (Bus Off Chip Off) which is controlled by ACPI. BACO was conceived as a power saving feature, but we also use it for reset since the chip gets powered down. These patches are a pre-requisite for using BACO as a power saving feature which will follow in another patch set. BACO is working well on VI parts. I haven't gotten it working yet on CI parts, but I'm including the code for reference if anyone wants to play with it.
