Load detection needs the connector wired to a CRTC, when there are no
inactive CRTCs left that means we need to cut some other head off for
a while, causing intermittent flickering.

Allows us to remove a driver hack that used to be necessary to disable
encoders in certain situations before setting up a mode. The DRM has
better knowledge of when this is needed than the driver does.
This fixes a number of display switching issues.

Uncertain if this is a weirdo configuration, or a BIOS bug. If it's not
a BIOS bug, we still don't know how to make it work anyway so ignore a
"conflicting" DCB entry to prevent a display hang.

As long as we know the length of the opcode, we're probably better off
trying to parse the remainder of an init table rather than aborting in
the middle of it.

Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector. This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.
This can also potentially modify the connector ordering on nv50. On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged. However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

We just need to clear the SBA and ENABLE bits to reset the AGP
controller: If the AGP bridge was configured to use "fast writes",
clearing the FW bit would break the subsequent MMIO writes and
eventually end with a lockup.
Note that all the BIOSes I've seen do the same as we did (it works for
them because they don't use MMIO), OTOH the blob leaves FW untouched.

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.
