Tested these patches on Lenovo Thinkpad P50. Audio works, the HDA and GPU
suspend when unused with no errors in logs and resume when needed.
HDA unbind/bind worked with no errors, some "Too big adjustment {128,3=
84}"
messages in dmesg.

For this hardware, even a plugged in HDMI TV on boot does not cause the aud=
io
device to appear, so the test was done with a PCI early quirk like suggeste=
d in
this bug.
