Previously we added i2c buses as needed when enumerating connectors
power management, etc. This only exposed the actual buses used and
could have lead to the same buse getting created more than once if
one buses was used for more than one purpose. This patch sets up
all i2c buses on the card in one place and users of the buses just
point back to the one instance.

This connector attribute allows you to enable or disable underscan
on a digital output to compensate for panels that automatically
overscan (e.g., many HDMI TVs). Valid values for the attribute are:
off - forces underscan off
on - forces underscan on
auto - enables underscan if an HDMI TV is connected, off otherwise
default value is auto.

This fixes a regression caused by b2ea4aa67b
due to the way shared ddc with multiple digital connectors was handled.
You generally have two cases where DDC lines are shared:
- HDMI + VGA
- HDMI + DVI-D
HDMI + VGA is easy to deal with because you can check the EDID for the
to see if the attached monitor is digital. A shared DDC line with two
digital connectors is more complex. You can't use the hdmi bits in the
EDID since they may not be there with DVI<->HDMI adapters. In this case
all we can do is check the HPD pins to see which is connected as we have
no way of knowing using the EDID.

v3: add config lock take inside polling, add intel/nouveau poll init/fini calls
v4: config lock was a bit agressive, only needed around connector list reading.
otherwise it could re-enter.

On systems with the tv dac shared between DVI and TV,
we can only use the dac for one of the connectors.
However, when using a digital monitor on the DVI port,
you can use the dac for the TV connector just fine.

This breaks the connection between the core drm connector list
and the fbdev connector usage, and allows them to become disjoint
in the future. It also removes the untype void* that was in the

v2 - Set proper mode type flags
v3 - Note that this is not neceesarily the exact panel mode,

registers or add a mode table, but this works and is much
simpler.

Some systems have multiple connectors connected to the same encoder;
e.g., DVI and HDMI connected to the same encoder with the same ddc
line. Since we expose connectors as xrandr outputs, randr treats them
separately which results in it trying to source the same encoder to
different crtcs. If we have an HDMI and DVI-D port on the same encoder,
pick the one to be considered connected based on the edid (HDMI if edid
indicates HDMI, DVI otherwise).
