This essentially (unless the link becomes unstable and needs to be
re-trained) gives us a single entry-point to link training, during
supervisor handling, where we can ensure all routing is up to date.

An upcoming commit will limit link training to only when the sink is
meant to be displaying an image.

We still need IRQs enabled even when the link isn't trained (for MST
messages), but don't want to train the link unnecessarily.

The aim here is to protect the OR against locking up when something

Upcoming commits make supervisor handling share code between the NV50
and GF119 implementations.  Because of this, and a few other cleanups,
we need to allow some additional customisation.

In order to properly support the SOR -> SOR + pad macro separation
that occurred with GM20x GPUs, we need to separate OR handling out
of the output path code.

This will be used as the base to support ORs (DAC, SOR, PIOR).

Now that we have the InfoFrame data being provided, for the most
part, program the hardware to use it.

While we're here, and since the functionality will come in handy
for supporting 3D stereoscopy, implement setting the Vendor
("generic"?) InfoFrame.

Also don't enable any InfoFrame that is not provided, and disable
the Vendor InfoFrame when disabling the output.

HDMI InfoFrames are passed to NVKM as bags of bytes, but the
hardware needs them to be packed into words.  Rather than having
four (or more) copies of the packing logic introduce a single copy
now, in a central place.

We currently need these for AVI and Vendor InfoFrames, but we may
also expect to need them for Audio InfoFrames at some point.

The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode.  These days, it
uses a fixed set of InfoFrames.  Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.

At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).
