[PATCH 00/15] Add BACO support for CI/VI asics

[Alex Deucher]

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.
