Alex Fiestas reported an issue with his HDMI connector being misdetected
as DVI unless he had something connected upon boot. By moving the
decision as to whether to use HDMI or DVI encoding for the HDMI capable
output until we probe the monitor means that we should avoid sending a
HDMI signal to a DVI monitor and also correctly detect hardware like
Alex's.

However, to really determine what connector is soldered onto the wire we
need to inspect the VBT sdvo child devices - but can we trust it?

Some voltage swing/pre-emphasis level use the same value on eDP
Sandybridge, like 400mv_0db and 600mv_0db are with the same value
of (0x0 << 22). So, fix them, and point out the value if it isn't
a supported voltage swing/pre-emphasis level.

Since Linux 2.6.36 the digital output on my system (855GME + DVI-I) is
not working any longer. The analog output is always activated
regardless of the type of monitor attached.

The culprit seems to be intel_crt_detect_ddc(), which returns true as
soon as an ACK from the EDID device is received. Obviously this
approach does not work with DVI-I where the analog and digital outputs
share a common DDC bus.

In a similar manner to the shared DDC wire, ala the "Mac Mini Hack", we
need an additional check to make sure that there really is an analog
device attached to the DDC.

When trying to do channel equalization, we need to make sure we still
have clock recovery on all lanes while training.  We also need to try
clock recovery again if we lose the clock or if channel eq fails 5
times.  We'll try clock recovery up to 5 more times before giving up
entirely.

Gets suspend/resume working on my Vaio again and brings us back into
compliance with the DP training sequence spec.

Lots of HDMI TVs overscan the incoming image by default.
The underscan option was added as a way to compensate for
that by underscanning the image so that the edges would
not be cut off on an overscanning TV.  However, the TV
provides no way of knowing whether it is overscanning or
not.  If the user has disabled overscan on their TV or has a
TV that does not overscan, you will get black bars around the
edges of your screen.  Prior to the patch we got complaints
and bug reports from users with overscanning TVs, now with
the patch, we get lots of complaints and bug reports from
users with non-overscanning TVs.  There's no good default,
but on average there have been more users complaining about
it being on by default than off, so change it to off.  This
will probably result in a new deluge of overscanning TV user
complaints.  There's no winning.

NI chips no longer load the MC ucode in the asic_init sequence so
the asic comes up in a basic mode with low engine/memory clocks and
a voltage.  Once the MC ucode is loaded by the driver the card
can be programmed to it's proper default clocks and voltage.  As such
the default clocks in the firmware info table as the post clocks, not
the default running clocks.  Track the default post clocks and default
running clocks separately to handle this.
