Now that highlevel DRM no longer requires PCI, we can move the requirement

On cards where there's a specific BAR for PRAMIN, we used to try and fall
back to the "legacy" aperture within the mmio BAR.

This is doomed to cause problems, so lets just fail completely as there's
obviously something else very wrong anyway.

Some of the laptops with the switchable graphics, seem to not post the secondary GPU at all, and we can't find a copy of the BIOS anywhere except in the ACPI rom retrieval.

When selecting the native mode for a display we weren't taking into account
whether or not it was actually supported on that particular output.

This patch modifies our native mode selection to run all modes through

We totally fail at detecting un-POSTed chipsets prior to G80.  This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.

NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

We may not have parsed the entry yet if the i2c_index is for an i2c bus
that's not referenced by a DCB encoder.

This could be done oh so much more nicely, except we have to care about
prehistoric DCB tables too, and they make life painful.

We really want to be able to distinguish between INIT_DONE and an actual

There appears to be some kind of switch on certain chips to control whether
the DP auxch or traditional i2c bus will be operational on a connector,
this commit hopefully fixes nouveau to do the right thing.

Likely only relevent on chips with DP outputs.
