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).

Reusing the list_head for both is a bad idea. Callback execution is done
with the lock dropped so that alarms can be rescheduled from the callback,
which means that with some unfortunate timing, lists can get corrupted.
The execution list should not require its own locking, the single function
that uses it can only be called from a single context.

The idea here was to avoid having to "manually" program the HW if there's
a new earliest alarm. This was lazy and bad, as it leads to loads of fun
races between inter-related callers (ie. therm).
Turns out, it's not so difficult after all. Go figure ;)

At least therm/fantog "attempts" to work around this issue, which could
lead to corruption of the pending alarm list.
Fix it properly by not updating the timestamp without the lock held, or
trying to add an already pending alarm to the pending alarm list....
