This is about to become somewhat more complicated to determine in a
number of cases, so store the "common" case (DDC/AUX) directly inside
the encoder structure.

Pre-nv50 code not touched except to fill the pointer, don't care.

Not quite how I want it yet, but, I'll fix that at some point.  For
right now, it's needed because find() won't necessarily be used right
before a transaction anymore.

"data" is a void pointer and "args" is "data" after we have casted it to
a struct.  We care about the size of the struct here.  Btw,
sizeof(*data) is 1.

Now can be used to operate on any buffer mapped into the GPU virtual
address and not just the main inter-channel sync buffer.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Allows most of the code to be shared between nv84/nvc0 implementations,
and paves the way for doing emit/sync on non-VRAM buffers (multi-gpu,
dma-buf).

Generated if you try and use fifo method 0x20 on any subchannel, appears
that it can be safely masked off without stalling the whole GPU.

Current uninitialized sensor detection does not work for me on nv4b and
sensor returns crazy values (>190°C). It stabilises later, but it's too
late - therm code shutdowns the machine...
