This has received light testing on NV18 and NV34 cards, using the modetest
tool. Userspace support to use this for xv is not yet ready.
I decided against creating a new "pvideo" engine -- that just seems way too
heavy-handed compared to the ~10 lines of code in disp/nv04.c to deal with the
PVIDEO interrupts.
Even though there are two possible planes, they are sufficiently linked
together that I decided to just expose them as one, and do a
double-buffering-style thing, similar to what xf86-video-nouveau did pre-KMS.
